Abrasive Grain Application:
Brown fused alumina (A)
It is made by fusing bauxite in an electric arc furnace under high temperature.
Feature: Good amount of toughness, hardness and self-sharpening. Great entry price.

Zirconia Alumina (ZA)
It is made by fusing alumina and zirconia with electric arc furnace under high temperature.
Feature: Highly wear resistant, very durable, self-sharpening, outperform brown fused alumina.
Application: General metal, stainless steel.

Black Silicon Carbide (C)
Black silicon carbide uses silica sand andpetroleum coke as raw material. The mixture is synthesized with Acheson process.
Hardness: Lower than diamond, higher than brown fused alumina.
Feature: Sharp, high hardness, brittle.
Application: Non-ferrous metal, non-metal material, masonry, cement, wood.
