Top-selling Refractory Material White Fused Alumina

1. White Fused Alumina Description

1)White Fused Alumina is made by first grade alumina as raw material, smelting in electric arc furnace at high temperature.

2)Wilead brand White Fused Alumina products’ features are as follows:corundum crystals is good, volume density, high purity, good temperature, acid alkali corrosion is strong.

3)White Fused Alumina hardness is higher but toughness lower compared with Brown Aluminum Oxide.

4)White Fused Alumina is characterized by high purity, excellent self-sharpening, efficient grinding efficiency, and low frictional heat.

5)White Fused Alumina can withstand acid and alkali erosion, with high temperature resistance and good thermo stability.
