WFA Macro Blasting

Description:

KWAMB is a kind of white fused alumina electrically fused in arc furnace with high grade processed alumina as raw material. It has higher hardness and slight lower toughness comparing with brown fused alumina.It is also characterized by its high purity, ability of self-harpening, better cutting,less heat emit, higher efficiency, acid and alkali resistance, good thermal stability.

Applications:

KWAMB is suitable for making abrasive stone, oil stone or for refractory coating and anti-skid tile, as loose grains, it widely used for pressure blasting and polishing.
