Tilting Furnace Barmac Crushed White Fused Aluminum Oxide WFA for Coated Abrasives
Tilting Furnace Barmac Crushed White Fused Aluminum Oxide WFA for Coated Abrasives
1. White Fused Alumina Descriptions
White Fused Alumina (WFA) is a high purity, synthetic mineral, made by the fusion of controlled quality pure grade Bayer Alumina in an electric arc furnace at temperatures higher than 2000˚C accompanied by a time consuming solidification process. Strict quality control of raw materials and fusion parameters ensure WFA with high purity and high whiteness.
2. White Fused Alumina Characteristics
a. High hardness
b. High purity
c. Direct manufacturer
d. Stable Chemicals
e. High whiteness
3. White Fused Alumina Packing
1). 25 kg/bag, in bulk;
2). 25 kg/bag, 40 bags/big bag;
3). 25 kg/ bag, 40 bags/pallet;
4). According to customer's requirement
4. White Fused Alumina Applications
White Fused Alumina is the most friable grain in the fused alumina family. It is considerably harder than BFA. Commonest used in Vitrified Bonded Abrasives products where cool, fast cutting and grinding of tool, high-speed and stainless. It is also in the manufacture of high purity Alumina refractories. Other applications include use in Coated Abrasives, Surface treatment, Ceramic Tiles, Anti-Skid Paints, Fluidized Bed Furnaces and Skin / Dental Care.
