SUOYI supply white alumina metal polishing powder in various grit sizes.
Polishing Powder / Metal Polishing Powder ( polishing powder, grinding and polishing micro powder) is an abrasive consumable made from ultra-fine hard inorganic powder.
It relies on micro-particle physical grinding to remove scratches, oxide layers, rust spots, and water stains from metal surfaces, achieving a matte/mirror-like high-gloss effect. Available in multiple grit sizes for coarse, medium, fine, and mirror polishing.

2. Silicon Carbide
Strong cutting force, mostly used for coarse grinding, removing deep scratches, and rust removal from hardware.
3. Chromium Oxide (Green Polishing Powder)
Ultra-fine, specially formulated for mirror polishing of stainless steel and mold steel, achieving a high gloss finish.
4. Rare Earth Polishing Powder (Cerium Oxide)
For fine brightening of gold, silver, and platinum jewelry, soft metals, and for polishing automotive glass. Also has a slight chemical polishing effect.
