Aluminium-Lithium Master Alloy Description
Pre-alloys are semi‐finished products that can be manufactured in various forms. They consist of a pre-alloyed mixture of alloying elements. Depending on their intended use, they are designated as modifiers, hardeners or grain refiners. These pre‐alloys are utilised in aluminium wrought alloys and cast alloys to adjust composition and to control microstructure.
Lithium is the least dense metal. The addition of lithium as an alloying element to aluminium reduces the alloy's specific gravity and increases its stiffness, while retaining high strength and corrosion resistance.
Stanford Advanced Materials supplies a complete range of alloys for the global aluminium industry, including the Aluminium-Lithium master alloy.

Aluminium-Lithium Master Alloy Applications
Hardening agent: Used to improve the physical and mechanical properties of metal alloys.
Grain refiner: Employed to control the dispersion of individual crystals in metals in order to produce a finer and more uniform grain structure.
Modifiers and special alloys: Used to increase strength, ductility and machinability.
Packaging of Aluminium-Lithium Master Alloys
Our Aluminium-Lithium Master Alloys are handled to minimise damage during storage and transport, thereby ensuring the product retains its quality.
