Aluminum 7075 Machining
Aluminum 7075 Machined Parts
Sunhy has a reputation for machining quality parts from Aluminum alloy 7075. We can machine intricate parts on our CNC Swiss machines and CNC turning centers.
Aluminum alloy 7075 is the strongest of available aluminum alloys, excellent for jobs that require extreme strength while remaining lightweight. It possesses great cracking resistance and increases in strength as temperature decreases, making it ideal for the aerospace industry.
Aluminum 7075 has a machining cost factor of 0.9 when compared to steel 12L14. It can be forged and heat treated, but is not ideal for welding. 7075 can be heat treated, annealed, and aged. It is not as ideal for anodizing compared to Aluminum 6061 and may produce a yellowish tint when clear anodizing.
