Aluminum boron master alloy AlB8

Master alloys are semi-finished products, and can be formed in different shapes. They are 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 disired result. They are used instead of a pure metal because they are very economical and save energy and production time.

Al-B master alloy used for grain refineing of casting Aluminum alloys and for purification of EC grade Aluminum alloys. Our Iran customers also use Al-8B master alloy in composite core for ACCC (Aluminum conductor composite core) cables.
