Aerospace

Because of low density, high strength, good corrosion resistance, good formability, and a series of advantages, Aluminium alloys become the significantly aerospace materials and are widely used in aircraft wing, fuselage, skin, etc.

The main aluminium alloys applied in aerospace are: 2xxx, 5xxx, 6xxx, 7xxx

Yonghong Aluminum not only has the ability to manufacture large size, high performance aerospace plate, but also can focus on research of the following two aspects:
1) Optimization to the original alloys:
    a). Improving purity of alloy, reducing impurity content
    b). adding trace element, narrowing scope of alloy composition
    c). Perfecting and improving manufacturing technique
2) Develop special performance alloy: for some special requirement, e.g.: temperature, environment, technology, etc..
