TM-WA Series White Fused Alumina Abrasive

TM-WA Series White Fused Alumina Abrasive

    Taking commercial alumina as raw material, white fused alumina is made by electric arc furnace melting. After it is crushed, ground and classified, fused white alumina abrasive of different size can be produced. Its color is white.
Features:
    It has high hardness, strong grinding force and wide application. Micro hardness can reach 2200~2300kg/mm2.
Applications:
    1)Decorative material polishing: Abrasive tools made of this abrasive material are suitable to grind high-carbon steel, high-speed steel and other thin wall parts.
    2)Polishing material: Abrasive powder is directly used in polishing materials and other precision casting sand.
    3)Spraying material: It is used in plasma spraying.
    4)Special ceramics and superior refractory products
Models:
W0.5~W63, 4#~240#, etc.
