As a typical representative of super hard metal, the high hardness of tungsten carbide is the best choice for wear-resisting parts, especially the spool, spool sleeve and other wear-resisting parts required by the automatic use of precision equipment. The precision of the product itself is high, and the wear-resisting performance of cemented carbide is prominent. The cemented carbide produced by powder metallurgy technology has the advantages of high strength, high hardness, wear resistance, corrosion resistance, high temperature resistance, low linear expansion coefficient and so on. It is widely used in many industrial production and processing operations, and is one of the excellent tool materials. Good physical stability, especially wear resistance, hard alloy material performance is particularly outstanding. For the core working part of precision equipment, hard alloy wear-resistant parts are widely used. The spool, spool sleeve, plunger rod, plunger sleeve and other precision parts that need to slide back and forth for a long time are used on the dispensing valve. The use of hard alloy as the material basis is a very good choice.
