Efficient White Corundum Abrasive Material for Versatile Applications

Product Description

White fused alumina/White aluminium oxide (WA) is electrically fused in the furnace with high grade bayer processed alumina as raw material..It has high purity,ability of self-sharpening,better cutting,less heat emit,higher efficiency,acid and alkali resistance,good thermal stability.Abrasives tools made of it are suitable for grinding high-speed,high carbon steel ,etc.It also can be used as materialsfor grinding and polishing,precision casting,spaying and coating, medium body for chemical industry,special ceramics and high-grade refractory materials,etc.
CIPIE White Aluminum Oxide (WFA) has high compression strength, high toughness, excellent self-sharpening, low coefficient of thermal expansion, and excellent hydrophilia and cleanliness. It is a clean, high-strength material that resists oxidation and corrosion, maintains chemical stability, and withstands extraordinarily high temperatures.
