Stanford Materials Corporation (SMC) supplies superior aluminum cerium master alloys with high purity and specific material characteristics. Customized shapes and component ratios of aluminum alloys are available upon request.
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 cerium master alloy is the alloy of Aluminium and cerium which is used as an additive for Cerium in aluminum alloys as a hardener. This alloy is dissolved fast in aluminum melt and gives a maximum recovery of Cerium than the cerium added individually.
Aluminum cerium master alloy has been added experimentally in casting alloys (eg. AlSiMg alloy,...etc) to increase fluidity and reduce die sticking. By adding cerium into the alloy, the strength and hardness at the room as well as high-temperature increase. Besides that, it also helps to refine the eutectic structure, decrease ductility, harden by dispersion(by precipitation of Al4Ce phase.), and influence the rate and precipitation of solid phrase. Cerium increases the recrystallization temperature of aluminum if Ce> 0.5%.
