36 mesh black fused alumina grit for sandblasting
Introduction
Black aluminum oxide fused corundum is also known as low aluminum corundum. It is also a new
type product of polishing material, and it is a dark gray crystal body made α-Al2O3 and ferropicotite
as main ore in the electric arc furnace by smelting the bauxite. It has characteristics of moderate
hardness, high toughness, high temperature resistance, and stable thermal stability. It is mainly
suitable for free grinding, such as coarse grinding before electroplating products, mainly for polishing
and sandblasting of stainless steel, fabricated metal products.
Application
1.free grinding ,such as glass industry
2.friction products and abrasion resistance ground
3.refractory material and fire-proof products
4.grinding stone , grinding block ,sand paper ,sand cloth ,sand belt
5.sandpaper and sandblasting ,wet and dry blasting
ducing mold of precision casting and polishing media
Commonly used size : 0-1mm 1-3mm 3-5mm 5-8mm 200# 320# or as your required
