Tilting Furnace Barmac Crushed White Fused Aluminum Oxide for Resin Abrasives
Tilting Furnace Barmac Crushed White Fused Aluminum Oxide for Resin Abrasives
1. White Fused Alumina Descriptions
White Fused Alumina (WFA) is obtained from the fusion of high purity calcined alumina in electric arc furnaces. WFA is raw material characterized with high hardness, yet friable with high purity, chemical stability, a high melting point, and large crystal size.
2. White Fused Alumina Characteristics
a. High hardness
b. High purity
c. Good performance
d. Stable Chemicals
e. No explosion while using
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
High chemical purity (>99% Al2O3) of WFA is generally softer or more friable than other abrasives, which can be used in grinding applications where a more friable product is desired. Granules typically are blocky shaped, with an aspect ratio of approximately 1:1 to 3:1; High purity (>99.5% Al2O3) of WFA, made by growing individual crystals from seed crystals at high temperature. Crystals are hexagonal platelet shaped with an aspect ratio of 5:1. Used in a variety of lapping, buffing and polishing applications, integrated into bars and pads, and used in ceramics.
