Al 7075

Aluminum 7075 is a zinc-aluminum alloy renowned for its exceptional mechanical strength and hardness. Frequently used in aerospace, automotive, and military sectors, this alloy is ideal for applications requiring high strength and lightweight properties. While it has lower corrosion resistance than other aluminum alloys, CNC milling allows for precise machining, producing complex components with high-quality surfaces.
