Introduction
Master alloys are semi-finished products, and can be formed in different shapes. They are a pre-alloyed mixture of alloying elements. They are also known as modifiers, hardeners, or grain refiners based on their applications. They are added to a melt to achieve the desired result. They are used instead of a pure metal because they are very economical and save energy and production time. The following datasheet will discuss about aluminium/aluminum silicon master alloy.
