  • APPLICATION    For stainless steel polishing

Firstly, the black Emery powder #90-#220 is used for sand blasting, grinding and polishing of various stainless steel, ordinary steel, copper, aluminum, bamboo, glass and other workpieces, especially on the polishing treatment of stainless steel surface, the effect is more prominent. .


It can also be converted into a sanding belt by using black emery powder into an abrasive cloth, and various abrasive products such as a sponge block, a resin grinding wheel, and a nylon wheel are used for polishing.


Secondly, the workpiece needs to be ground and polished. When there is a certain grinding requirement, the black emery powder can be compounded with other abrasives grits with higher hardness and better wear resistance to make polishing wheels, fiber wheels, abrasive belts, etc. The effect is better than using black emery powder only, and the cost performance is higher.


Key Notes: Using black emery powder for polishing, especially for stainless steel surface polishing, use pure black emery powder; if for polishing& grinding, can be used with other abrasive like brown fused alumina, Calcined brown fused alumina, single crystal fused alimina, etc, the effects are better, cost-effective!
