Introduction
Master alloys are a pre-alloyed combination of alloying elements that are available in different forms. They are also known as grain refiners, hardeners or modifiers based on their applications. They are used instead of a pure metal because they are very economical and save energy. They can be added to a melt to achieve the desired result. These alloys are suitable for structure control and adjusting the composition of a liquid metal in order to achieve the required chemical specification.
The following datasheet gives an overview of aluminium/aluminum yttrium master alloy.
