White Fused Alumina

With over two decades of specialized experience in the Abrasive Media Industry

White Fused Alumina

White fused alumina, produced from industrial alumina fused at high temperatures, is renowned for its exceptional hardness compared to brown fused alumina, though it possesses lower toughness. This makes white fused alumina ideal for abrasive tools used in grinding high carbon steel, high-speed steel, and chilled steel. It is also versatile enough to serve as polishing media, precision foundry sand, spraying and coating materials, catalyst carriers, special ceramics, and high-grade refractory materials.

When considering white fused alumina price, it’s essential to factor in its superior performance and the value it adds across various applications. The white fused alumina price reflects its advanced manufacturing process and high-quality standards, offering a cost-effective solution for industries requiring precise and durable abrasive materials. Investing in white fused alumina not only ensures high efficiency but also supports long-term performance in demanding applications.
