                                   Aluminum-Lithium Alloy (Al Li alloy)
Aluminum-lithium alloy is a new material in aviation and aerospace. It is the most rapidly developing field in aviation metal materials in recent decades. 

Our company as the leader manufacturer of Al-Li alloy in china, Coperated with Boeing company.We has provided numerous high-grade precise aluminum products for the domestic Spaceships, Carrier Rockets etc of China’s aerospace industry

Provided large amount of aluminum and its alloy plates, sheets, strips, tubes, rods and bars, profiles and forgings for the China’s aviation and aerospace industry.


Provided large amount of aluminum products with high performance of pre-stretching plates, forgings, profiles, rods & bars for passenger plane, helicopter, sky truck etc of aviation industry.

Product advantage:

1. low density, reduce weight, and saving cost.

2. High specific modulus, high specific strength,can instead of the high strength aluminum alloy to reduce 10% - 20%, Increase the modulus and stiffness of elasticity

3. Excellent corrosion resistance

4. Good thermal conductivity and electrical conductivity
