WFA Coated (Iron or zirconium)
WFA Coated
(Iron or zirconium)
Description
Coated WFA is a special abrasive made from high-quality WFA as raw material, which is coated with a layer of metal iridium composite material (Iron or zirconium)on the surface of the WFA through high temperature and heat treatment, and then calcined to produce it. After coated, the toughness of WFA is significantly improved, the surface is rougher, the hydrophilicity is stronger, the self sharpening ability is increased, and the heat dissipation performance is improved. In the process of making grinding wheel products, it can be better combined with binders. The produced grinding tool products have high work efficiency, long service life, and are not easy to burn the workpiece.
Applications
- Fixed grinding tools such as cutting blades, ultra-thin blades, large blades, polishing blades, and grinding blades
- Spraying materials
- Apply grinding tools such as sandpaper, sanding cloth, sanding belt, sponge grinding block, fiber polishing wheel
