Master alloys are of different shapes and they are referred to as semi-finished products or base metals that include copper, nickel or aluminum combined with a higher percentage of one or two of other elements.
Master alloys are used to determine a metal’s microstructure during solidification and casting to change its properties that include electrical conductivity, surface appearance, ductility, mechanical strength or castability. Master alloys are also used to obtain a specific chemical specification by changing the liquid metal’s composition.
Copper-based master alloys have better dissolving capacity in comparison with pure metals. Copper-zirconium, copper-iron, copper-boron and copper-manganese also make up the list of copper-based master alloys.
The following datasheet provides an overview of copper-tellurium master alloy.
