White Fused Alumina with Al2O3 99% min
Description:
White fused alumina with Al2O3 more than 99% is a kind of high-grade refractory, which is made from the high quality alumina by melting above 2,000 in the electric arc furnace and cooling.
White fused alumina is an extremely sharp, long-lasting blasting abrasive that can be recycled many times after the initial media blasting. It is the most widely used abrasive in blast finishing and surface preparation because of its cost, longevity and hardness. Harder than other commonly used blasting materials, white aluminum oxide grains penetrate and cut even the hardest metals and sintered carbide.
Application:
Refractory materials
Abrasive tools
Lapping, polishing, non-skid tile and pressure blasting
