7075 F is a zinc-based aluminum alloy commonly used in applications requiring high strength. The designation "F" indicates that the alloy is in the "As Fabricated" condition, meaning it has not undergone any special heat treatment and is used in its formed state. This alloy is widely utilized in aerospace, defense, automotive, and sporting equipment industries.
7075 alloy is known for its exceptional strength and fatigue resistance. Compared to many other aluminum alloys, it is significantly harder, though it has lower weldability and machinability. Due to its susceptibility to corrosion, it is often used with surface treatments or coatings.
Thanks to its high strength-to-weight ratio, 7075 F is an ideal choice for structural and critical engineering applications. It also performs well in precision machining for components requiring tight tolerances.
