Introduction
Master alloys are semi-finished products available in a variety of shapes. These alloys are referred to as grain refiners, modifiers or hardeners based on their usage. In comparison with pure metals, master alloys are more economical. Master alloys also save production time and energy as they dissolve faster when made to work under lower temperatures.
Master alloys are used to obtain a specific chemical specification by changing the liquid metal’s composition and also used to determine a metal’s microstructure during solidification and casting.
Copper-based master alloys have better dissolving capacity in comparison with pure metals. Copper-based master alloys also include copper-zirconium, copper-iron, copper-boron and copper-manganese.
The following datasheet provides an overview of copper-antimony master alloys.
