What is Zirconia Fused Alumina ?
Zirconia Fused Alumina (ZFA), also commonly called zirconia alumina or zirconium aluminum oxide, is a high-performance fused abrasive material manufactured by co-melting high-purity bauxite and zirconia sand together in an electric arc furnace at extreme temperatures above 2000°C. After molten solidification, the ingot goes through crushing, screening, magnetic separation and strict grading processes to form standardized abrasive grains. It is recognized as one of the toughest fused abrasives on the market, sitting between brown fused alumina and silicon carbide in application scenarios yet delivering far superior fatigue resistance.
What is the difference between brown fused alumina and white fused alumina?
Brown Fused Alumina (BFA) and White Fused Alumina (WFA) are two of the most important abrasive materials, but they have distinct differences in composition, properties, and applications.
What is fused alumina used for?
Fused alumina, a synthetic material produced by melting and recrystallizing high-purity alumina (Al₂O₃) in an electric arc furnace, is a workhorse industrial abrasive and refractory material. Its extreme hardness (9.0-9.2 on the Mohs scale), high melting point, and chemical inertness make it indispensable across numerous industries.
What is Brown Fused Alumina(BFA)
Brown fused alumina is made from Calcined Bauxite. It is a hard and tough material, used in manufacturing of grinding wheels (both vitrified and resin bonded) and coated products.
These grains are also used for shot blasting and as polishing media.
Refractory grade BFA is used as a raw material in the manufacture of high alumina refractory.
What is brown aluminum oxide
Brown aluminum oxide is a normal brown color emery sand,made from calcined bauxite.
What are the usages of brown fused alumina in sandblasting?
Brown fused alumina (BFA) is a high-hardness, tough, and eco-friendly blasting abrasive with sharp angular grains and excellent self-sharpening performance, industrial surface cleaning and rust removal,precision surface finishing, matting,deburring,edge chamfering and recyclable eco-friendly blasting treatment.
