Product Description

WHITE FUSED ALUMINA FOR MATTE EFFECT SANDBLASTING

Full series of abrasive for bonded abrasives are available in our factory, including Black fused alumina, brown fused alumina, black fused alumina.

All these three abrasive can be used for bonded abrasives, here are differences among them.

Abrasive/Difference	Color	Al2O3	Hardness	Toughness	Application in bonded abrasives
White fused alumina 2810109000	White	99%	Highest	Not high, Brittle	Full WA abrasives, or mixed with BFA
Brown fused alumina 2810101000	Brown	95%	High	Good Toughness	Full BFA abrasives, or mixed with WA or BA
Black fused alumina 2818101000	Black	62%	Moderate	Best toughness	Using mixed with BFA

GRAIN SIZES AVAILABLE
12#, 14#, 16#, 20#, 24#, 30#, 36#, 46#, 54#, 60#, 70#,80#, 90#, 100#, 120#, 150#, 180#, and 220#

Abrasive	Hardness	Toughness	Materials suitable for grinding	Features
White fused alumina	Higher	Little Lower	precision hardened steel, high carbon steel, high speed steel and ground thin-walled parts.	When grinding, the abrasive particles are easily broken, so the grinding heat is small.
Brown fused alumina	High	High	grinding metals with high tensile strength, such as carbon steel, alloy steel, malleable cast iron, hard bronze, etc.	It has good grinding performance. Often used for rough grinding with large margin and widely used.
Black fused alumina	Lower	Highest	carbon steel, alloy steel, malleable cast iron,	Adding15%-30% black fused alumina with BFA to produce cutting discs can improve work life and the incision quality and reduce production cost.
