White Fused Aluminum Oxide (WFA) is characterized with high hardness, yet friable with high
purity, chemical stability, a high melting point, and large crystal size.
To be used for Bonded abrasives and Coated abrasives.
Ceramic coated White Aluminum Oxide, Ceramic coating improves its purity and hydrophilicity, reduces dust, and makes the abrasive grain has greater toughness and higher hardness. Sinabuddy supply two kinds of Ceramic coated Red WFA (WFA-RCC), and Ceramic coated White WFA (WFA-WCC)
