Fused Zirconia Alumina (Zirconium Oxide) ZA-25 and ZA-40 has become one of the most important raw materials in advanced abrasive applications and high-performance refractory systems. With excellent toughness, high fracture strength and outstanding thermal stability, zirconia alumina has been widely adopted in grinding heavy-duty metals, stainless steel, alloy steels and wear-resistant components.

Fused zirconia alumina is produced by fusing zirconium oxide and aluminum oxide at high temperature. The final abrasive grain offers superior self-sharpening behavior, making it highly durable in aggressive grinding environments.
This material is available in ZA-25 and ZA-40 grades, offering multiple performance options depending on application requirements.
