.063 Aluminum Sheet| 4×8 3003 5052 6061 | Buy Near Me

What Is .063 Aluminum Sheet?

A .063 aluminum sheet measures 0.063 inches thick. That equals 1.6 millimetres.

In the gauge system, this is close to 16 gauge. The sheet weighs roughly 0.9 pounds per square foot.

A standard 4×8 sheet weighs about 28.7 pounds. This thickness sits in the middle range. It is thick enough for structural use. Yet it is thin enough to bend with hand tools or a brake press.

Many buyers search for .063 aluminum sheet because it hits a sweet spot. It offers good strength without the weight of thicker plates. It also costs less than heavy-gauge options.

This makes it one of the most popular thicknesses in the metal supply market.

How Thick Is .063 Aluminum Sheet?

The .063 measurement is exact. It is not an estimate.

Unit	Value
Inches	0.063″
Millimetres	1.6 mm
Gauge (approximate)	16 gauge
Fraction	1/16″

Note: Some suppliers list .063 as 1.6 mm. Others round it to 1.5 mm. Always ask for the exact decimal when ordering. Tolerance is usually ±0.003″.

Weight of .063 Aluminum Sheet

Weight depends on the alloy. Different alloys have slightly different densities.

Alloy	Density	Weight per sq ft	Weight of 4×8 sheet
3003	2.73 g/cm³	~0.90 lbs	~28.8 lbs
5052	2.68 g/cm³	~0.88 lbs	~28.2 lbs
6061	2.70 g/cm³	~0.89 lbs	~28.5 lbs

Quick Formula: Weight (lbs per sq ft) = Thickness (inches) × 144 × Density (g/cm³) × 0.0361

For .063″ 3003: 0.063 × 144 × 2.73 × 0.0361 ≈ 0.90 lbs/sq ft.

Alloy Types for .063 Aluminum Sheet

Not all .063 sheets are the same. The alloy changes how the sheet behaves.

3003-H14: The General-Purpose Choice

3003 Aluminum Sheet is the most common alloy at this thickness. It contains manganese. This gives it better strength than pure aluminium.

Property	Value
Main Alloy Element	Manganese (1.0 – 1.5%)
Temper	H14 (half hard)
Tensile Strength	22,000 psi
Yield Strength	21,000 psi
Elongation	8% min
Best For	Roofing, siding, ductwork, signs

Why It Sells: 3003-H14 is affordable and easy to work. It bends well in a brake press. It also resists corrosion in normal outdoor air. Many HVAC shops and sign makers keep this grade in stock.

---

5052-H32: The Marine-Grade Option

5052 adds magnesium. This makes it stronger and more salt-resistant than 3003.

Property	Value
Main Alloy Element	Magnesium (2.2 – 2.8%)
Temper	H32 (quarter hard, stabilized)
Tensile Strength	33,000 – 42,000 psi
Yield Strength	28,000 psi
Hardness	70 Brinell
Best For	Boat parts, fuel tanks, outdoor panels

Why It Sells: 5052-H32 is the top pick for anything near water. It resists salt spray better than 3003. The H32 temper also allows tight bends without cracking. Fabricators use it for marine trim, truck bodies, and chemical tanks.

---

6061-T6: The Structural Grade

6061 is heat-treatable. It contains magnesium and silicon. The T6 temper gives it high strength.

Property	Value
Main Alloy Elements	Magnesium (0.8 – 1.2%), Silicon (0.4 – 0.8%)
Temper	T6 (solution heat treated and aged)
Tensile Strength	42,000 – 45,000 psi
Yield Strength	35,000 – 40,000 psi
Hardness	93 – 95 Brinell
Best For	Brackets, frames, machine parts

Why It Sells: 6061-T6 is roughly twice as strong as 5052-H32. It machines cleanly and holds tight tolerances. The trade-off is lower bendability. For bending, order 6061-O or T4 temper. Bend first, then heat treat to T6 if needed.

---

6061-T651: The Stress-Relieved Version

T651 is the same as T6 but with stress relief. The sheet is stretched after heat treatment. This removes internal stress.

Property	Value
Temper	T651
Flatness	Better than T6
Machining	Excellent, less warping
Best For	Precision tooling plates, CNC work

Why It Sells: CNC shops prefer T651 because it stays flat during machining. T6 can warp when milled. T651 solves this problem.

Common Product Types for 6063 Aluminum

The 6063 aluminum plate or sheet is available in several forms. Each type is optimized for a specific industrial or decorative need.

Mill Finish 6063 Sheets

This is the standard, untreated form of the alloy. It has a natural, slightly shiny metallic look. It is often used as a base material for further fabrication or when the metal will be hidden from view.

Anodized 6063 Aluminum Sheet

Because 6063 is so pure, it takes anodizing beautifully. Anodizing creates a hard, protective layer that can be dyed in colors like clear (silver), black, bronze, or gold. This is the top choice for modern building facades.

Painted and Powder Coated Sheets

For projects requiring specific branding or colors, 6063 serves as an excellent substrate. The smooth surface allows paint to bond perfectly, ensuring no peeling or bubbling over time.

Brushed 6063 Aluminum

A mechanical brushing process creates a linear texture on the sheet. This is very popular for high-end interior design and decorative panels. It diffuses light and hides fingerprints.

Temper and Hardness Options for 6063

The temper of the 6063 aluminum sheet dictates how it reacts to pressure and bending.

6063-O (Annealed)

This is the softest state. It is very easy to bend into tight radii. However, it has very low strength. It is used when extreme forming is required before heat treatment.

6063-T4 (Solution Heat Treated)

This temper offers a middle ground. It has good formability and will naturally age over time to become harder.

6063-T5 (Cooled from Extrusion/Rolling)

T5 is common for products that are cooled and then artificially aged. It provides good mechanical properties and excellent dimensional stability.

6063-T6 (Artificially Aged)

This is the most common temper for 6063 aluminum. It provides the maximum strength possible for this alloy while maintaining a high-quality surface.
