Product Overview

Aluminum zirconium master alloy is a specialized grain refiner used to improve the mechanical properties of aluminum and aluminum-based alloys. The addition of small percentages of zirconium helps refine the grain structure of cast alloy ingots, resulting in more uniform aluminum products with improved mechanical consistency.

While aluminum is widely used across industries, its mechanical properties in pure form are insufficient for many structural applications. Alloying elements such as zinc, copper, and silicon are commonly used to increase strength through heat treatment, while zirconium is added in small amounts to control grain structure and improve resistance to recrystallization.

Master alloys offer the most effective method for introducing zirconium into aluminum melts. These pre-alloyed materials contain known, controlled amounts of zirconium (typically in the 2–3 wt. percent range), ensuring consistent results and homogeneous composition in the final product.

White Abrasives supplies aluminum zirconium master alloy with 2.5% zirconium content, produced by alloying zirconium into molten aluminum under controlled conditions, followed by casting into master alloy ingots.
