Aluminum Bismuth Master Alloy Description
Master alloys are semi-finished products and can be formed in different shapes. They are a pre-alloyed mixture of alloying elements. They are also known as modifiers, hardeners, or grain refiners based on their applications. These master alloys are used in aluminum wrought alloys and foundry alloys for composition adjustments and structure control.
Aluminum Bismuth Master Alloy is added to aluminum alloys as a bismuth additive. Bismuth forms the free machining phase which is not soluble in aluminum and not forms intermetallics compounds with aluminum. The formed heterogeneous phases cause discontinuity of the matrix.
Stanford Advanced Materials offers a complete range of alloys for the global aluminum industry including the Aluminum Bismuth master alloy.

Aluminum Bismuth Master Alloy Application
- Hardeners: Used for enhancing the physical and mechanical properties of metal alloys.
- Grain Refiners: Used for controlling the dispersion of individual crystals in metals to produce a finer and more uniform grain structure.
- Modifiers & Special Alloys: Typically used to increase strength, ductility, and machinability.
