Introduction
Master alloys are defined as a pre-alloyed mixture of alloying elements. They are formed in different shapes, and are used as raw material in metal industries. Based on their applications, they are also referred to as a grain refiner, a modifier or a hardener. A pure metal is usually replaced by master alloys because they are very economical.
Master alloys are added to a melt to obtain the desired result. They are semi-finished products, and base metals that can be mixed with other elements with higher percentage.
The following datasheet will discuss about copper-iron master alloy.

Applications
Copper-iron master alloy is used as a grain refiner for some brass alloys and aluminium bronze. It is also used for improving mechanical properties of low alloyed coppers and corrosion resistance of copper-nickel alloys.
