密封面材料-超硬合金SIC/TC.....

    The commonly used wear-resistant materials (Carbide) for mechanical seals are roughly divided into silicon carbide (SIC) and tungsten carbide (TC). SIC can be subdivided into R-SIC, S-SIC and G-SIC, and tungsten carbide can be divided into nickel and Cobalt is two kinds of binding agents.
