Introduction
Master alloys are also known as modifiers, hardeners, or grain refiners based on their applications. They are semi-finished products, and are available in different forms. They are base metals, which can be mixed with other elements. They are used instead of a pure metal because they are very economical.
The following datasheet gives an overview of copper-lithium master alloy.
