刹车片耐磨粉天然铬铁矿粉200目Chromite Flour 200 grit
刹车片耐磨粉天然铬铁矿粉200目Chromite Flour 200 grit是一种天然尖晶石，以南非的48含量高品位铬铁矿砂为原材料。 进口的铬铁矿在国内经过粉碎，磁选，研磨和筛分后，将其分为更细的颗粒和粉末。 加工后的铬铁矿粉含量不低于46%，同时具有很好的耐磨和耐高温性能。它适用于用于诸如汽车制动器之类的耐磨部件的防滑或耐磨材料。
Brake pad wear-resistant powder, natural chromite powder 200 mesh Iron Chromite Flour 200 grit is a natural spinel made from high-grade chromite sand with a content of 48 in South Africa. Imported chromite ore is crushed, magnetic separated, ground, and screened in China, and then divided into finer particles and powders. The content of processed chromite powder is not less than 46%, and it has good wear resistance and high temperature resistance. It is suitable for anti slip or wear-resistant materials used for wear-resistant components such as car brakes.
