The reliable default for machined aluminum parts.
6061-T6 offers a strong combination of availability, dimensional stability, weldability and anodizing performance. It is often the best starting point when a design does not require the higher strength of 7075 or the corrosion behavior of a marine alloy.
- 01Fixtures, housings, brackets and structural frames
- 01Robotics, electronics and industrial equipment
- 01Good response to clear and color anodizing
- 01Broad stock-form and thickness availability
Choose 6061 for balance—not maximum strength.
Compared with 7075-T6, 6061 is lower in strength but easier to weld, generally less expensive and more corrosion resistant. Critical bearing surfaces, thin walls and fatigue-loaded features still require application-specific review.
- 02Prefer 7075 when strength-to-weight dominates
- 02Prefer 5052 for formed sheet components
- 02Consider hard anodize for wear surfaces
- 02Protect electrical contact areas from insulating finishes

Can 6061 be anodized?+
Yes. 6061 responds well to Type II decorative anodizing and Type III hard anodizing. Color and dimensional buildup should be specified before machining.
Is 6061 stronger than 7075?+
No. 7075-T6 is substantially stronger, while 6061 is typically easier to weld, more corrosion resistant and more economical.
