6063 Aluminum Composition
The chemical composition of 6063 aluminum alloy determines its balance of strength and formability.
| Element | Content (%) |
|---|---|
| Aluminum (Al) | 97.5% – 99.0% |
| Magnesium (Mg) | 0.45% – 0.9% |
| Silicon (Si) | 0.2% – 0.6% |
| Iron (Fe) | ≤ 0.35% |
| Copper (Cu) | ≤ 0.10% |
| Manganese (Mn) | ≤ 0.10% |
| Chromium (Cr) | ≤ 0.10% |
| Zinc (Zn) | ≤ 0.10% |
| Titanium (Ti) | ≤ 0.10% |
This precise composition allows 6063 aluminum to achieve a smooth finish and good anodizing response.
6063 Aluminum Bendable
One of the key advantages of 6063 aluminum is its excellent bendability and formability.
It can be easily bent, rolled, or formed into various shapes without cracking — especially in T4 or T52 temper.
Best tempers for bending:
- T4 → For deep bends and curves
- T52 → For standard forming
- T6 → For limited bending (may require heat assistance)
For tight bends, annealing or using a smaller temper like T4 is recommended.
6061 vs 6063 Aluminum Sheet
Both 6061 and 6063 belong to the same aluminum-magnesium-silicon series but serve slightly different purposes.
| Feature | 6061 Aluminum | 6063 Aluminum |
|---|---|---|
| Strength | Higher | Moderate |
| Formability | Medium | Excellent |
| Surface Finish | Good | Very smooth |
| Machinability | Excellent | Good |
| Weldability | Excellent | Excellent |
| Common Use | Structural parts, frames | Architectural profiles, panels |
Choose 6061 for mechanical parts and 6063 for architectural or decorative uses.

The Differences Between 6061, 6063, and 7075 Aluminum Sheet
| Alloy | Series | Strength | Corrosion Resistance | Weldability | Main Uses |
|---|---|---|---|---|---|
| 6061 | 6xxx | High | Very Good | Excellent | Frames, aircraft, tools |
| 6063 | 6xxx | Medium | Excellent | Excellent | Architectural, profiles |
| 7075 | 7xxx | Very High | Moderate | Poor | Aerospace, defense parts |
6063 offers the best mix of beauty and corrosion resistance, while 7075 is reserved for high-stress applications.
Deep Dive: Alloy 6061 – The “All-Rounder”
The 6061 aluminum alloy is the most widely used aluminum in the world. It is often called “Structural Aluminum.” It offers a perfect balance of strength, corrosion resistance, and price.
Why choose 6061?
- Versatility: It can be extruded, rolled into sheets, or forged into complex parts.
- Great Welding: Unlike higher-strength alloys, 6061 is very easy to weld using standard techniques.
- Reliability: It handles environmental stress very well without cracking.
Main Uses for 6061:
- Transport: Bicycle frames, truck trailers, and marine hulls.
- Infrastructure: Bridges, railings, and heavy-duty frames.
- Industrial: Machine parts, jigs, and fixtures.
- Aircraft: Non-critical structural components.
Deep Dive: Alloy 6063 – The “Architectural Star”
If your project requires a beautiful finish and complex shapes, 6063 aluminum is your best choice. It is slightly softer than 6061 but is much easier to push through an extrusion die to create intricate designs.
Why choose 6063?
- Surface Aesthetics: It is the best alloy for anodizing. It produces a smooth, clean, and colorful finish.
- Corrosion Power: It has the highest resistance to outdoor elements among these three.
- Extrudability: It can be formed into very thin and complex cross-sections.
Main Uses for 6063:
- Architecture: Window frames, door frames, and curtain walls.
- Interior Design: Furniture, trim, and decorative moldings.
- Electrical: Heat sinks (due to its good thermal conductivity).
- Profiles: Custom tubing and lightweight rails.
Deep Dive: Alloy 7075 – The “Powerhouse”
When strength is the only thing that matters, 7075 aluminum is the king. This alloy uses Zinc as its primary element. It is one of the strongest aluminum alloys available, comparable to some types of steel.
Why choose 7075?
- Highest Strength: It can handle extreme stress and pressure.
- Fatigue Resistance: It lasts a long time under repeated heavy loads.
- Weight Savings: Because it is so strong, you can use thinner pieces to achieve the same strength as steel.
Main Uses for 7075:
- Aerospace: Aircraft wings and fuselage structures.
- Defense: Missile parts and military gear.
- High-End Sports: Professional rock-climbing equipment and bicycle gears.
- Tooling: High-pressure molds for the plastics industry.
Mechanical Properties: The Numbers Behind the Metal
For engineers, the “Digital Specs” are vital. Here is how they perform under pressure (typical values for T6 temper).
Mechanical Specs Table
| Property | 6061-T6 | 6063-T6 | 7075-T6 |
|---|---|---|---|
| Yield Strength (MPa) | ~240 | ~170 | ~500 |
| Tensile Strength (MPa) | ~290 | ~215 | ~570 |
| Hardness (Brinell) | 95 | 73 | 150 |
| Elongation at Break (%) | 10−15% | 12−18% | 5−11% |
| Density (g/cm3) | 2.70 | 2.70 | 2.81 |
Fabrication Comparison: Welding, Machining, and Finishing
Choosing an alloy also depends on how you plan to manufacture your final product.
Welding Performance
- 6061 & 6063: Both are excellent for welding. However, welding can reduce the strength near the joint. You may need to re-heat-treat them.
- 7075: Generally considered “non-weldable” in a commercial sense.
Machining Performance
- 7075: Machines beautifully. It chips away cleanly, allowing for high-speed CNC work.
- 6061: Machines well, though it can be slightly compared to 7075.
- 6063: Because it is softer, it can be difficult to machine without the metal tearing or sticking to the tool.
Anodizing and Finishing
- 6063: The clear winner. It produces a high-gloss, uniform color.
- 6061: Anodizes well, but the color might be slightly duller than 6063.
- 7075: Can be anodized for protection, but the high zinc content can make the color look patchy or “muddy.”
