Aluminum-Zirconium (Al-Zr) Master Alloy | Professional Aluminum Grain Refiner

Vacuum-melted Al-Zr master alloy without rare earth elements. High-efficiency grain refiner for aluminum alloys, improving structural stability and mechanical performance. Custom grades with professional anti-oxidation packaging.

Our Aluminum-Zirconium master alloy is independently vacuum-melted in our Ganzhou factory. This product contains no rare-earth elements and serves as one of the most efficient grain refiners for aluminum alloys. It can significantly refine coarse aluminum grains, eliminate casting defects, and improve the uniformity, strength and thermal stability of aluminum alloy structures.

We supply standard industrial grades and support customized zirconium content. With ultra-low impurity control and stable component ratio, it is widely used in high-end aluminum casting and industrial modification fields.
