Technical properties of common aluminum alloys
Aluminum combines a low density with strong mechanical performance, excellent machinability, and useful corrosion resistance. Compare common grades before selecting the right material for your part, process, and operating environment.
| Alloy | Density (g/cm³) |
Tensile strength (MPa) |
Hardness (Brinell) |
Machinability | Weldability | Corrosion resistance | Typical application |
|---|---|---|---|---|---|---|---|
| 6061-T6 | 2.70 | 310 | 95 | Excellent | Excellent | Good | Structural parts, fittings, brackets |
| 7075-T6 | 2.81 | 570 | 150 | Good | Poor | Moderate | Aerospace and high-stress parts |
| 2024-T3 | 2.78 | 470 | 120 | Good | Poor | Moderate | Aircraft structures |
| 5052-H32 | 2.68 | 230 | 60 | Fair | Excellent | Excellent | Sheet metal and enclosures |
| 6082-T6 | 2.70 | 310 | 95 | Excellent | Excellent | Good | Automotive and structural parts |
| MIC-6 | 2.70 | 170 | 65 | Excellent | Good | Good | Tooling plates and jigs |

6061-T6 vs. 7075-T6
The right alloy balances strength, weight, cost, corrosion behavior, weldability, and finishing requirements. These two structural grades are common starting points for design reviews.
6061-T6 — the general-purpose workhorse +
Advantages: Versatile, cost-effective, highly weldable, and easily anodized.
Trade-off: Lower strength than 7000-series alloys.
Best for: Housings, consumer electronics, brackets, and general mechanical components.
7075-T6 — the high-performance alloy +
Advantages: High strength-to-weight ratio and excellent fatigue resistance.
Trade-offs: More expensive, difficult to weld, and requires careful handling to reduce stress-corrosion risk.
Best for: Structural aerospace parts, high-load gears, and precision fixtures.
CNC machining or sheet metal fabrication?
We select the most cost-effective route based on geometry, tolerance, production volume, and structural requirements.
