Brown fused alumina 0-1mm for refractory material PV:457
-
Category：Brown Fused Alumina
SPEC：Abrasives F16-F1200， P12-P1200， Refractory 0-1mm，1
Packaging：Bag Package/Small Bag Package
Brown fused alumina, with high quality bauxite as main material, features micro-hardness and is tougher than silicon carbide. It is suitable for the normal grinding, cutting-off and loose grain polishing of metal materials with high tensile strength, such as carbon steel, alloy steel, malleable cast iron and hard bronze. It is also a very practical advanced refractory material.
