Semi-Friable Aluminum Oxide

Semi-friable Aluminum Oxide, it produced by high quality bauxite as raw material, melted at the high temperature of above 2100℃ in the electric furnace, and using a special broken treatment technique. Since its hardness and toughness is between white fused aluminum Oxide and brown fused aluminum Oxide, it is called semi-friable fused aluminum oxide.

It is characterized by reasonable toughness, excellent self-sharpening, high temperature resistance, corrosion and erosion resistance, low apparent porosity and stable thermal stability.

In accordance with the current GB/FEPA/JIS sieve standards.

Application:

It can be used for making Vitrified /Ceramic abrasive tools, Resin abrasive tools and Coated abrasives.
For Rough Grinding, Semi-friable Aluminum Oxide can improve processing efficiency, and for accurate grinding, and can improve the work pieces’ surface quality.
The Bonded Abrasives made by Semi-friable Aluminum Oxide are featured of high durability, excellent self-sharpening performance and retain ability. It can be used for processing ordinary steel, bearing steel, all kinds of stainless steel, tool steel, low Cr/W/Mo/V/Co content special alloy steel, some cast iron and all kinds of non-ferrous metals.
The Coated Abrasives made by Semi-friable Aluminum Oxide have excellent sanding quality, long service life, and larger sanding quantity. It is mainly used for thermo sensitive metal and alloy, soft non-ferrous metal, etc. It can be also used for sanding wood, plastic coating, paint. Especially for hard wood, the effect is much better.
