The use of non-toxic silicon additions in aluminum smelting reduces the overall melting temperature, reduces brittleness, and increases heat resistance. Silicon additions will also improve structural properties because silicon reduces shrinkage in casting applications.
In copper alloys, silicon increases fluidity properties and helps reduce gas holes created during deoxidization. When added to brass, silicon increases strength and corrosion resistance all the while reducing electric conductivity.
Silrec can offer the aluminum smelting and metal alloy industries many different types of hi purity silicon additions with very low impurity.
