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.

| Applications |
1. Hardeners: Used for enhancing physical and mechanical properties of metal alloys.
2. Grain Refiners: Used for controlling the dispersion of individual crystals in metals to produce a finer and more uniform grain structure.
3. Modifiers & Special Alloys: Typically used to increase strength, ductility and machinability. |
