What effect does aluminium strontium alloy have?

 

Aluminum-strontium alloy can refine eutectic silicon and primary silicon in the alloy, improve the mechanical properties of the alloy, its metamorphism has good long-term performance, good remelting stability. The addition of strontium is generally controlled between 0.02 and 0.04%. For example, the content of strontium in aluminum strontium alloy is 10%, and the addition ratio is between 0.2 and 0.4%, which can guarantee the metamorphic effect. Generally, aluminum strontium alloy is added to the alloy, which is usually preheated to 200-300 degrees and then added in proportion after removing the corresponding others.
