Precision hard alloy products
Cemented carbide is a kind of alloy material which is made of hard compound of Refractory metals and bonding metal by powder metallurgy process.
It has high hardness, wear resistance, good strength and toughness.
Hard alloy can be used to make rock drilling tools, mining tools, drilling tools, measuring tools, wear-resistant parts, metal molds, cylinder liners, precision bearings, nozzles, and so on. Xidi hard alloy products mainly include nozzles, valve seats, valve sleeves, logging parts, valve trims, sealing rings, molds, teeth, rollers, rollers, etc.
