Sand Casting White Fused Aluminum Oxide Abrasive Grit F50 - F80 F70 - F140
Description:
white fused alumina electrically fused in arc furnace with high grade processed alumina as raw material. t is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency.
White fused aluminum oxide can be used for shell making material of heavy steel casting, especially the alloy casting, core sand, coating material and melt film precision casting.And white alumina is also can be used as half precision blasting and precision blasting material for hardened steel, alloy steel and so on.
White Fused Alumina For Sandblasting Abrasive Is Processed By High Quality Corundum From RSAbrasive Plant As Raw Material And Untilzed By Unique Advanced Technology.
