Scandium Aluminum Alloy

Aluminum alloy to add trace scandium can significantly improve the strength of the aluminum alloy, plastic toughness, high temperature resistant performance, corrosion resistance, weldability and neutron irradiation damage resistance, has been used as structural materials in areas such as aerospace, aviation, nuclear reactor, the ships, high-speed trains, light vehicles, and other fields has a wide application prospect.

In aerospace and aviation industry, the application of Al-Sc alloy develops rapidly.

In order to improve the comprehensive performance of large civil aircraft, aluminum-scandium alloy material has been used in some other countries to replace other materials in the load-bearing parts of large civil aircraft.

In the fields of nuclear industry and naval industry, Al Sc alloy has strong anti-neutron damage property and can be used in the structural parts of nuclear reactors.Because of its light weight, high stiffness, strong welding strength, low thermal cracking and excellent fatigue resistance, Al-Sc alloy has great potential in the application of ship bearing parts, structural materials for high-speed trains and oil pipelines.
