Four stages of the application of aviation aluminum alloys for sale Haomei

Aluminum, magnesium, titanium and other metals have low density and are often called light metals, and the corresponding aluminum alloys, magnesium alloys and titanium alloys are called light alloys. The special excellent properties and development potential of light alloys have prompted countries around the world to pay more and more attention to the research and development and promotion of light alloy materials. Today Haomei Aluminum Co., Ltd. takes you to understand aviation aluminum alloys, and their four stages in the development of aerospace applications. The application and development of aluminum alloy in aerospace can be divided into 4 stages:

First, the main goal in the 50s is to reduce weight and improve the specific stiffness and specific strength of the alloy;

Second, the main goal in the 60~70s is to improve the durability and damage tolerance of alloys, and develop 7XXX series alloys T73 and T76 heat treatment systems, 7050 alloys and high-purity alloys;

Third, the 80s required further weight reduction of structural weight due to the rise in fuel prices;

Fourth, from the 90s to the present, the development goal of aluminum alloy is to further reduce weight and further improve the durability and damage tolerance of the alloy.

For example, the development of a new aluminum alloy with high strength, high toughness and high corrosion resistance, a large number of thick plates processed into complex integral structural components instead of the components previously assembled with many parts, can not only reduce the weight of the structure, but also ensure the stability of performance. To achieve this, it is necessary to develop a thick plate material with low internal stress. We have gone through these four processes and currently produce advanced first-class aluminum alloys for aerospace. If you need to buy aviation aluminum alloy, please contact us Haomei.
