Dawb fused alumina (WA)
khoom Nthuav dav
1. White Fused Alumina (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.
Lub abrasive cov cuab yeej los ntawm WA yog tsim kev sib tsoo high-carbon steel, high-ceev hlau thiab chilled steel, thiab lwm yam Nyob rau hauv tas li ntawd, nws muaj peev xwm yuav tau siv rau polishing cov ntaub ntawv, precision casting xuab zeb, txau cov ntaub ntawv, tshuaj catalyst cab kuj, tshwj xeeb ceramics thiab high-qib refractories, etc.

2. Dawb fused alumina -Heated & Tej hub coated
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.
