Introduction
Master alloys are used globally, and are available in different shapes. They are semi-finished products consisting of a pre-alloyed mixture of many alloying elements. Based on their applications, they are also referred to as a modifier, a grain refiner, or a hardener. They are used as raw materials in metals industries.
