Black aluminium oxide abrasive(Lower Aluminium Oxide Abrasive)is a new type abrasive mateeial for polishing various metal works. It is electrical fused an arc furace from aluminium oxide as rew material. Black aluminium oxide abrasive is featured with high hardness. Strong ten aclty,good self-sharpening.better cohesisensee durability,less heat generated in grinding and giving the metal works high finish, less power weakened in grinding. It is mostly used in grinding and polishing stainless steel,metal works, optical glass,bamboo or articles. And it is also the new grinding material of producing colophony grinding wheels,slice,and emery cloth.
With high toughness,BA is extremely suitable for polishing stainless steel and non-ferrous metals.It's grinding efficiency is much higher than that of brown A/O and the finishing effect is much better than many of other abrasive materials.
