White Fused Alumina
Raw Material And Process Of Production:
White fused alumina/WFA is a high-quality raw material, made of fused refining crystal, high
purity, self-sharpening, good acid and alkali resistance, high temperature, thermal properties and
stability it is slightly higher than the corundum hardness, toughness slightly lower, high purity,
good self-sharpening, grinding ability, heat, high efficiency, acid corrosion, high temperature thermal
stability. Made with the abrasive, for grinding high-carbon copper, high-speed steel.
Based on the years of experience and expertise, we are engaged in manufacturing, supplying, trading and exporting a quality range of White Fused Alumina. These products are finely processed under hygienic conditions and are highly used in producing iron and steel industries. Our products are available in safe and hygienic packing.

Size:
Different size and different specification can be supplied according to customers’ requirements.
If you need requirement, please contact us.
The particle size of the product according to the international standards and national standards of production, according to user requirements for processing granularity. Universal size is F4~F220, w63-w2.5 and their chemical composition depending on the size and different. The prominent feature is the small crystal size, impact resistance, if broken from the processing mill, particles are spherical particles, the surface dry clean, easy to bond with.
Product Performance
White fused alumina Occupying higher hardness and slightly lower toughness compared with Brown Fused Alumina, it is characterised by its high purity, better cutting,ability of self-sharpening, less heat emit during grinding, higher efficiency,acid and alkali resistance, and good thermal stability. Abrasive tools made of it are suitable for grinding high-speed, high carbon steel,etc.
Application:
1, Apply to quickly remove the heat treatment of bearing rings, rolling surface of the oxide skin;
2, suitable for stamping, combined iron holder for chamfering and deburring, polishing for copper holder to completely replace the original pickling, polishing process for chamfering, deburring, polishing not only improve the quality of products, and improve the working environment, in accordance with the national environmental protection requirements.
3, apply to bearings, cylindrical roller, tapered roller, spherical roller, needle roller surface polishing, greatly improve the surface roughness and brightness
It also can be used as materials for grinding and polishing, precision casting, spraying and coating, medium body for chemical industry, special ceramics and high-grade refractory materials,etc.
