Chalco 7075 precision machined rolled aluminum plate is probably the most famous high-strength rolled plate, and is used regardless of the individual requirements in nearly all sectors of the capital goods industry. In material temper T7351, it is also suitable for application where there is a risk of stress corrosion cracking.
Characteristics of Chalco 7075 precision machined rolled aluminum plate:
1. Two surfaces preccision milled, roughness Ra 0.4um, foiled on both sides.
2. Fine surface miling as requirement. Good surface quality.
3. Very high strength
4. Ideally suitable for structural etching
5. Excellent polishing properties
6. Very good machinability
