Special Iron Sulfide For Brake Pads

Detailed introduction: ferrous sulphide ore (iron sulphidefine ore) is
filling agent for ablating grinding wheel abrasive, which can effectively
reduce the grinding wheel temperature during ablation, improve the heat
resistance, and prolong the service life of the grinding wheel.
