White Fused Alumina

Product Description

White fused alumina is made from industrial alumina powder, smelted at a high temperature of more than 2000 degrees in an electric arc, and then cooled. It is crushed and shaped, iron is removed by magnetic separation, and sieved into a variety of particle sizes. Its texture is dense, high in hardness, and the particles form sharp corners. Shape, suitable for manufacturing ceramics, resin-consolidated abrasive tools, as well as grinding, polishing, sandblasting, precision casting (corundum for precision casting), etc. It can also be used for manufacturing high-grade refractory materials

Application

1) For precision casting and high-grade refractory.

2) For bake lining, catalyst carrier, friction products

3) For pressure blasting hard abrasives; refractory industry

4) For wet and dry blasting, grinding, lapping and polishing media

5) For abrasive tools: grinding wheel, lapping and polishing non-skid title;

6) For bonded and coated abrasives, thermal spraying (Plasma Spraying)

7) For lapping & micro-blasting applications, refractories, ceramics and tiles.
