Aluminum Sheet/Plate 5052-H32 has normally application, for fuel, marine, automotive, and machine applications. It is renowned for its unparalleled corrosion resistance and workability.
What is 5052 H32 Aluminum Sheet
Like all the 5052 series of aluminum, the H32 is a good choice for welded construction when thickness demands are not too extreme and a mold or jig is not needed. In addition to its good formability, 5052-H32 will take permanent bends without developing fatigue cracks.
5052 aluminum sheet/plate has high tensile strength, good workability and fair corrosion resistance. It is non-magnetic in thicknesses up to 0.250″ and has a min yield strength of 0.020″.
How much is a sheet of 5052 aluminum?
Our 5052 aluminum sheet/plate is ideal for making air-intake ducts, automotive trim, shutters and doors, lawn furniture and swimming pool liners. Also great for housings, handrails, brackets, sign and display frames, motorboat engine mounts and building channel letters.
Breaking Down the 5052 Alloy
Chemical Composition
The recipe behind 5052 is precise. Each element plays a role in the final performance.
| Element | Content (%) | Role in the Alloy |
|---|---|---|
| Aluminum | 95.7 – 97.7 | Base metal, provides light weight and corrosion resistance |
| Magnesium | 2.2 – 2.8 | Main strengthening agent, improves corrosion resistance in seawater |
| Chromium | 0.15 – 0.35 | Refines grain structure, enhances stress corrosion cracking resistance |
| Manganese | 0.10 max | Minor grain control, improves workability |
| Iron | 0.40 max | Trace impurity, kept low to avoid strength loss |
| Silicon | 0.25 max | Trace impurity, affects castability but not sheet properties |
| Copper | 0.10 max | Kept very low to prevent galvanic corrosion issues |
| Zinc | 0.10 max | Minimal effect at this level |

The high magnesium content is the star here. It forms Mg2Al3 intermetallic particles that strengthen the matrix. It also builds a more protective surface oxide film than pure aluminum or 3003 alloy.
Key Physical Properties
| Property | Value | What It Means for You |
|---|---|---|
| Density | 2.68 g/cm³ | Lighter than 6061, easier to handle and ship |
| Melting Range | 607 – 650°C | Standard for aluminum, safe for most processes |
| Thermal Conductivity | 138 W/m·K | Good heat dissipation for heat exchanger uses |
| Electrical Conductivity | 35% IACS | Lower than pure aluminum but acceptable for many electrical apps |
| Coefficient of Thermal Expansion | 23.8 x 10⁻⁶ /°C | Similar to other aluminum alloys, predictable expansion |
| Elastic Modulus | 70.3 GPa | Stiff enough for structural panels, flexible enough to form |
H32 Temper Explained in Depth

Temper designations in aluminum are not random letters and numbers. They describe exactly how the metal was treated after rolling. Understanding H32 helps you avoid costly mistakes in fabrication.
How H32 Is Made
The journey starts with hot rolling. The cast ingot is heated and rolled down to near-final thickness. Then the sheet goes through cold rolling. This cold work hardens the metal. After cold rolling, the sheet is heated briefly to a low temperature. This stabilization step relieves some internal stress. The result is H32.
What H32 Delivers
| Characteristic | H32 Value | Comparison to Other Tempers |
|---|---|---|
| Tensile Strength | 214 – 262 MPa | Higher than H22, lower than H34 |
| Yield Strength | 159 – 193 MPa | Good balance of strength and ductility |
| Elongation | 8 – 12% | Enough for moderate forming operations |
| Hardness (Brinell) | 60 HB | Harder than annealed, softer than full-hard |
| Bend Radius (90°, 1.6 mm thick) | 1.5 x thickness | Tighter than H34, looser than O temper |
H32 vs Other 5052 Tempers
| Temper | Strength Level | Formability | Best Use Case |
|---|---|---|---|
| O (Annealed) | Lowest | Excellent | Deep drawing, complex shapes, maximum formability |
| H22 | Low | Very Good | Moderate forming, better stability than O |
| H24 | Medium | Good | General fabrication, painted panels |
| H32 | Medium-High | Good | Marine panels, exterior cladding, tanks |
| H34 | High | Fair | Structural panels, less forming needed |
| H36 | Very High | Poor | Minimal forming, high strength required |
| H38 | Highest | Very Poor | Flat panels only, maximum strength |
| H112 | As-rolled | Moderate | Plate applications, less critical temper control |
The H32 temper sits in the middle of the pack. It gives you more strength than H22. It gives you more formability than H34. For most marine and outdoor applications, this is exactly where you want to be.
5052 H32 Mechanical Properties in Detail
Numbers matter when you are engineering a structure. Here is the full mechanical profile of aluminum sheet/plate 5052 H32.
Tensile and Yield Strength by Thickness
| Thickness Range | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) |
|---|---|---|---|
| 0.2 – 0.5 mm | 214 – 262 | 159 – 193 | 8 min |
| 0.5 – 1.5 mm | 214 – 262 | 159 – 193 | 10 min |
| 1.5 – 3.0 mm | 214 – 262 | 159 – 193 | 12 min |
| 3.0 – 6.0 mm | 214 – 262 | 159 – 193 | 14 min |
| 6.0 – 12.5 mm | 214 – 262 | 159 – 193 | 14 min |
| 12.5 – 50 mm (plate) | 214 – 262 | 159 – 193 | 12 min |
| 50 – 80 mm (plate) | 214 – 241 | 138 – 186 | 10 min |
Notice how elongation improves in thicker sections. This is because thinner sheet work-hardens more during rolling. Thicker plate retains more ductility.
Fatigue and Impact Behavior
Table
| Property | Value | Notes |
|---|---|---|
| Fatigue Strength (5×10⁸ cycles) | 117 MPa | Excellent for cyclic loading like boat hulls |
| Charpy Impact (V-notch) | 20 – 25 J | Good toughness, resists sudden loads |
| Fracture Toughness (KIC) | 35 – 40 MPa√m | Better than many higher-strength alloys |
The fatigue number is especially important. A boat hull flexes with every wave. A tank wall flexes with every fill and drain. 5052 H32 handles this repeated stress far better than 6061-T6, which is stronger but more brittle under cyclic loads.
Thickness Options: From Foil-Thin Sheet to Heavy Plate
5052 H32 is available across a wide thickness range. The industry draws a line at 6.35 mm (0.25 inch). Below that, we call it sheet. Above that, we call it plate. Both share the same alloy and temper designation.

Fabrication Guidelines for 5052 H32
Working with this material is straightforward if you follow a few rules.
Bending and Forming
| Thickness | Minimum Bend Radius (90°) | Recommended Tool |
|---|---|---|
| 0.5 – 1.0 mm | 0.5 x thickness | Standard press brake, sharp die |
| 1.0 – 2.0 mm | 1.0 x thickness | Press brake with radius die |
| 2.0 – 3.0 mm | 1.5 x thickness | Press brake, generous radius |
| 3.0 – 6.0 mm | 2.0 x thickness | Heavy press brake, warmed if cold |
| 6.0+ mm (plate) | 2.5 – 3.0 x thickness | Hot forming recommended |
Welding
5052 H32 welds beautifully with both MIG and TIG processes.
| Welding Process | Filler Wire | Shielding Gas | Notes |
|---|---|---|---|
| MIG (GMAW) | ER5356 | 100% Argon | Fast, good for thick sections |
| TIG (GTAW) | ER5356 | 100% Argon | Cleanest welds, best for thin sheet |
| TIG (GTAW) | ER5556 | 100% Argon | Higher strength weld, marine preferred |
Important: The heat-affected zone near welds loses the H32 temper. It reverts toward soft annealed condition. For critical structural welds, post-weld heat treatment or design around the softened zone is needed.

| Milling | Carbide inserts with polished faces | Climb milling preferred, sharp edges |
| Turning | Carbide with positive rake angle | Continuous cut, avoid interrupted cuts |
| Tapping | Spiral flute taps, coated | Use tapping fluid, withdraw frequently to clear chips |
Cutting
| Method | Best For | Notes |
|---|---|---|
| Guillotine shear | Thin sheet, straight cuts | Clean edge, fast, no heat |
| Band saw | Plate, thick sections | Use carbide-tipped blade, slow speed |
| Circular saw | Plate, straight cuts | Carbide blade, 3000+ RPM for thin, slower for thick |
| Plasma cutting | Thick plate, complex shapes | Heat-affected zone needs cleanup |
| Waterjet | All thicknesses, intricate shapes | No heat distortion, best edge quality |
| Laser cutting | Thin to medium sheet | Fast, precise, slight HAZ |

Diverse Product Types in 5052 H32
Not every Aluminum Sheet/Plate 5052 H32 looks the same. Depending on your needs, we offer various surface finishes and physical forms.
Plain Mill Finish Sheets
This is the raw metal. It has a smooth, slightly dull silver surface. It is the most economical choice. It is perfect for parts that will be hidden or parts that you plan to paint yourself.
5052 Aluminum Tread Plate (Diamond Plate)
We also produce Aluminum Sheet/Plate 5052 H32 with a raised diamond pattern. This is often called “Checker Plate.” Because 5052 is so resistant to corrosion, these tread plates are commonly used for boat decks and dock ramps.
Anodized 5052 Sheets
Anodizing adds a thick oxide layer to the surface. This increases scratch resistance and allows for different colors. It is very popular for architectural panels and high-end electronic enclosures.
Perforated 5052 Aluminum
These sheets have patterns of holes punched through them. Because 5052 H32 is strong, these sheets maintain their structural integrity even with many holes. They are used for filters, grilles, and soundproofing panels.



What Makes 5052 H32 Different?
5052 is part of the 5000 series of aluminum alloys. The main ingredient added to the aluminum base is magnesium. Small amounts of chromium and manganese join the mix. Together these elements create a metal that laughs at saltwater and shrugs off fatigue.
The H32 temper tells a specific story. The “H” means the metal was strain-hardened. The “3” means it was stabilized after hardening. The “2” means it sits at quarter-hard strength. This temper hits a sweet spot. It is stronger than soft annealed sheet. Yet it still bends and forms without cracking.
In plain terms, 5052 H32 is the grade you pick when you want marine-level durability without giving up the ability to shape the metal by hand or machine.
Critical Comparisons: 5052 vs. Other Alloys
When choosing a metal, it helps to compare it to other popular options. This ensures you are not overspending or choosing a material that is too weak.

Frequently Asked Questions
Is 5052 H32 aluminum marine grade?
Yes, it is one of the most popular marine-grade alloys. Its high magnesium content protects it from the corrosive effects of salt water and humid sea air.
Can I bend 5052 H32 aluminum?
Yes. The H32 temper is designed for formability. You can bend it to a tight radius without worrying about the metal cracking, which is a major advantage over the 6061 alloy.
Does 5052 aluminum rust?
Aluminum does not rust like steel, but it can oxidize. 5052 forms a very stable protective layer that prevents deep corrosion. It is highly resistant even in wet or chemical environments.
What is the difference between sheet and plate?
In the aluminum industry, anything thinner than 0.250 inches (6.35 mm) is called a sheet. Anything 0.250 inches or thicker is called a plate. We provide both in the 5052 H32 specification.
Is 5052 H32 Suitable for Saltwater Environments?
Yes. This is one of its primary strengths. The high magnesium content forms a protective surface film that resists chloride attack from seawater. It outperforms 3003, 6061, and most other common alloys in marine splash zones. For complete immersion, 5083 or 5086 offer even better resistance, but 5052 H32 handles intermittent wetting and salt spray with ease.
Can I Bend 5052 H32 Sheet by Hand?
Thin sheet up to about 1 mm can be bent by hand with a bending brake or even over a sharp edge with mallet assistance. Thicker sheet requires mechanical assistance. The H32 temper allows reasonable forming, but remember that work-hardening occurs with each bend. If you need to make multiple complex bends, consider ordering O temper sheet and forming it before converting to H32 if needed.
What Is the Difference Between 5052 H32 Sheet and 5052 H32 Plate?
The only difference is thickness. The aluminum industry defines sheet as material from 0.2 mm up to 6.35 mm thick. Plate is 6.35 mm and thicker. Both share the same alloy chemistry and H32 temper. Both offer the same corrosion resistance. Plate is simply thicker and used where more structural depth or machining stock is needed.
Will Welding 5052 H32 Reduce Its Strength?
Yes, locally. The heat from welding destroys the H32 temper in the heat-affected zone. That zone reverts to near-annealed condition with much lower strength. The unaffected material retains full H32 properties. For structural welds, engineers often specify thicker material near welds or use backing structures to compensate for the softened zone.
How Does 5052 H32 Compare to Steel for Marine Use?
Table
| Factor | 5052 H32 Aluminum | Mild Steel | Winner |
|---|---|---|---|
| Weight (same volume) | 2.68 g/cm³ | 7.85 g/cm³ | 5052 H32 |
| Corrosion in saltwater | Excellent (no rust) | Poor (requires painting) | 5052 H32 |
| Raw material cost per kg | Higher | Lower | Steel |
| Total lifecycle cost | Lower (no painting) | Higher (maintenance) | 5052 H32 |
| Strength-to-weight ratio | Good | Lower | 5052 H32 |
| Weldability | Excellent | Good | Tie |
Over a 20-year boat life, aluminum almost always wins on total cost due to eliminated painting and repair.
Can 5052 H32 Be Anodized Successfully?
Yes, and it anodizes very well. The alloy produces a clear, uniform anodic coating. The coating accepts dyes consistently. Type II anodizing yields decorative colors. Type III hardcoat anodizing produces a wear-resistant surface ideal for marine hardware. The only caveat is that welded areas may anodize slightly differently due to altered microstructure.
What Thickness Should I Choose for a Boat Hull?
Hull thickness depends on boat size, design, and classification society rules. General guidelines:
Table
| Boat Length | Recommended Bottom Thickness | Recommended Side Thickness |
|---|---|---|
| Under 4 meters | 2.0 – 2.5 mm | 1.5 – 2.0 mm |
| 4 – 6 meters | 2.5 – 3.0 mm | 2.0 – 2.5 mm |
| 6 – 10 meters | 3.0 – 4.0 mm | 2.5 – 3.0 mm |
| 10 – 15 meters | 4.0 – 5.0 mm | 3.0 – 4.0 mm |
| Over 15 meters | 5.0 – 6.0+ mm | 4.0 – 5.0 mm |
Always consult naval architecture standards like ABS, Lloyd’s Register, or DNV for certified vessels.
Is 5052 H32 Magnetic?
No. Aluminum is non-magnetic in all its alloys. This makes 5052 H32 ideal for applications near compasses, MRI machines, or sensitive electronic equipment where magnetic interference must be avoided.
Can I Paint 5052 H32 After Installation?
Yes, but preparation is key. The natural oxide layer must be lightly abraded or chemically etched. Use a primer specifically formulated for aluminum. For marine applications, epoxy primers followed by polyurethane topcoats offer the best protection. However, pre-painted 5052 H32 from the mill often provides better adhesion and longer life than field-applied paint.
What Is the Shelf Life of 5052 H32 Sheet?
Practically unlimited if stored correctly. Keep sheets dry, flat, and away from moisture. Stack on a level surface to prevent distortion. Separate sheets with paper or plastic to avoid abrasion. In proper storage, 5052 H32 will maintain its properties for decades. The natural oxide layer protects the underlying metal from slow degradation.
