White
Aluminium Oxide (WFA) is obtained from aluminum oxide calcined which is high
purity . White Aluminum Oxide is the most important character features have
high hardness and large crystal size, chemical resistance, high melting points.
Fragility due to their high level of purity is very small. White
aluminum oxide has a resistance that can be used for a long time, high hardness
and also has a structure that can resist high pressure, are resistant to wear. Because
of their purity is 99% and over, they are a little harder and durable then
Brown Aluminum Oxide abrasives.
