1. White Fused Alumina (WA)
Code: WA
White Fused Alumina is made from Aluminium Oxide powder. It is electrically fused in high temperature. It is white. Comparing with Brown fused alumina, its hardness is a little higher, but its toughness is little lower. Our WA has the features of stable quality, well-distributed particle size composition, low magnetic substance content, high bulk density and toughness, and high cleanliness, etc.
The abrasive tools made by WA are suitable for grinding high-carbon steel, high-speed steel and chilled steel, etc. In addition, it can be also used for polishing materials, precision casting sand, spraying materials, chemical catalyst carrier, special ceramics and high-grade refractories, etc.

2. White fused alumina -Heated & Ceramic coated
CODE: BC-WFA-HCC
WFA-HCC is ceramic coated with ferric oxide on the surface by a specific processing. It is made from high quality white fused alumina calcined at high temperature through intensive deep processing. The product features a large specific surface area, stronger hydrophilicity, even particle size, higher purity, stronger binding power, cutting effciency and good heat dispersion performance, it's main performance indexes are as below: compared with normal BFA, BFA-HCC micro-hardness increases 10%, toughness increases 10%, hydrophilicity increase 3.5 times, grinding and cutting quantity increases 3% and efficiency increase 30%-50%.
It is the best choice and very popular for making top grade resin cut-off wheels.
Standard: FEAP F (Bonded abrasives)
Grit available: Grit F12 – F220#. Other sizes are also available on request.
