Introduction
Master alloys are semi-finished products that are used as raw materials in metal industries. These alloys are preferred over a pure metal because they are very economical and save energy. They are a pre-alloyed mixture of many alloying elements. They are added to a melt to achieve the desired result. They are suitable for structure control and composition adjustment. Master alloys are also known as grain refiners, modifiers, or hardeners based on their applications.
The following datasheet gives an overview of aluminium/aluminum copper master alloy.
