White Fused Alumina(WFA),also called White Fused Aluminum Oxide, named by its white color, belongs to the electro fused artificial corundum group. It’s an important mineral with chemical and high temperature stability, great purity, hardness and fireproof and refractory characters. White fused alumina is one of the most widely used raw materials for so many industrial fields, including refractory, bonded abrasives and coated abrasives industries.
We are professional manufacturer for customers in different industries and countries according to FEPA, JIS, GB, ISO standard. 0-1mm, 1-3, 3-5mm etc. for refractoriness, FEPA F sizes for bonded abrasives aluminum oxide tools, FEPA P sizes for coated abrasives aluminum oxide products
White Fused Alumina Typical Characters
High Alumina Content
White Fused Alumina has Aluminum Oxide(Al2O3) content of more than 99%, which guarantee the great performance in fireproof and refractory application
High Purity
White Fused Alumina has very limited impurities, usuallyNa2O≤0.4%,SiO2≤0.15% andFe2O3≤0.15%.
High Hardness
The high content of Al2O3 (Aluminum Oxide) obtains White Fused Alumina Mosh Hardness of 9 and wide application for cutting and grinding wheels, also, White Fused Alumina can be used for coated abrasives, sandblasting media for surface preparing and polishing of metallic and ceramic products.
Sharp Edges
White Fused Alumina is a crystal mineral with sharp edges and widely used in sandblasting, cutting and grinding abrasives.
