Product CodeSC-AF02
It is one kind ofspecially BrownFused Alumina grain for abrasivesapplication.
Brown fused alumina is fused in a special ace furnnace, namedtiltingfurnace.The
Lump made from this kind of furnace have the very small crystalthan Fixed
Furnace,so the products have the higher toughness and better anti-impactability, it
It is well used in vitrified application and can improve thegrinding efficiency.

ProductCode SC-AF03
The grains of this type ofBrown Fused Alumina are heated at800°C-1,200°C and thepurpose is to renovate the crack on the surface and interior ofcrystal and then to improve the toughness and anti-impact abilityof grain. After re-treated, the product can increase the using timeof the bonded abrasives products. The appearance of the grain islow blue colour.

Product CodeSC-AP06
This kind of BFA is used for coated abrasive products. Thegrain
Shape is very sharp, the strip and needle shape are well kicked offfrom the grains. it can be used for producing all kinds of coatedproducts, such as sand paper , cloth, rolls, belts, etc.
it also can be heated at800°C-1,200°C and thepurpose is to renovate the crack on the surface and interior ofcrystal and then to improve the toughness and anti-impact abilityof grain.
