7050 aluminium sheet/plate 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 replaces Cr with Zr to overcome the quenching sensitivity problem and inhibit recrystallization. 7050 aluminium sheet is an alloy that has been around for decades and is known for its ability to remain strong over time. Although other alloys are available which are stronger on a one-off comparison basis, but they do not necessarily prove the longevity which the 7050 products can offer.

Applications and Features:

1. Compared with 7075 aluminium sheet, 7050 aluminium 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 aluminium sheet is not good, but it can be processed.

4. 7050 aluminium sheet also has good anodizing reaction.

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

The Use of 7050 Aluminium Sheet

The 7050 aluminium sheet is primarily designed for the aerospace industry, but can also be used in other applications that require high strength aluminum.

Main use

Aircraft structural parts. Used for medium and heavy plate extrusion, free forging and die forging. Common applications for 7050 aluminium 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.

Other uses

It can also be applied to various molds, fixtures, mechanical equipment and high-end aluminum alloy bicycle frames.
