7050 H112 Aluminum Sheet

7050 aluminium sheet is a high-strength heat-treatable alloy. It is based on 7075 aluminium alloy, which increases the Zn, Cu content and Cu / Mg ratio to increase the strength, and it replaces Cr with Zr to overcome the quenching sensitivity problem and inhibit recrystallization. 7050 aluminium sheet is an alloy that has been existing for decades and is known for its ability to remain strong over time.

Specifications of 7050 Aluminium Sheet

Chemical Composition of 7050 Aluminium Sheet

The Features of 7050 Aluminium Sheet

1. Compared with 7075 aluminum sheet, 7050 aluminum has higher corrosion resistance and better toughness.

2. Has lower quenching sensitivity. This allows it to maintain its strength properties, stress corrosion cracking resistance and fracture toughness levels.

3. The cold workability of 7050 aluminum sheet is not good, but it can be processed.

4. 7050 aluminium sheet also has a good anodizing reaction.

5. Welding methods are not recommended, such as brazing, gas shielded arc welding or coated metal arc welding.

Applications of 7050 Aluminum Sheet

Typical Usage：Aircraft structural parts. Used for medium and heavy plate extrusion, free forging and die forging. Common applications for 7050 aluminum sheets include bulkheads and fuselage frames that require a cross-sectional thickness of between 2 and 6 inches. Another common application is for wing skin. Most applications of this metal are for thicknesses greater than 2 inches, which makes this metal an excellent choice. It can also be applied to various moulds, fixtures, mechanical equipment and high-end aluminium alloy bicycle frames.
