Product Description
High Quality White Aluminum Oxide Fused Alumina(WA/WA-B/WA-P/WA-R) Corundum Abrasives, Special Specifications Customizable!
White Fused Alumina (WA) is produced by bayer alumina in an electric arc furnace at high temperatures. The product shows higher hardness, higher bulk density and good cleanliness. The materials can be used to grind high carbon steel, high speed steel, chilled steel and so on. It can also be used as polishing materials and precision founding sand, spraying and coating materials, catalyst carrier, special ceramics and super refractory materials.
White Corundum/White Aluminum Oxide/White Fused Alumina are applied into many industrial fields due to its stable and great physical and chemical properties. It can be used for making bonded/coated abrasive tools, for grinding, polishing, lapping, blasting, precision casting, and refractory industry, aerospace industry, mobile phone and electronic industry, jewelry industry, hardware industry, ceramics, automobile parts, bearing, powder metallurgy and so on.
Note: Special requirements on chemical composition and other terms can be satisfied through discussion.
The grit sizes of White Corundum/White Aluminum Oxide/White Fused Alumina WA WFA are produced according to national standard and international standard, and can be also produced according to customers' requirements.
Note: Special requirements on chemical composition and other terms can be satisfied through discussion.
Product package: 25kg P. P Bag+1MT Jumbo Bag, 25kg Paper Bag+1 MT Pallet, or according to customers' requirements.
