2018-04-25 15:03
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

Application of Chalco7075 precision machined rolled aluminum plate:

Mold-making, in particular blow molds for plastics processing and PUR foam molds are preferably made of rolled plate EN 7075.

Mechanical engineering, tool carriers, tool changers, tool clamps, etc, 7075 precision machined rolled aluminum plate is always used.

Tool making, highly loaded anvil caps, punch retainer and embossing plates are often made of 7075 precision machined rolled aluminum plate.

Industrial robots, different versions of gripping claws, clamping and tensioning devices for heavy loads are produced by 7075 precision machined rolled aluminum plate.
