Cemented carbide punch is a part of the cemented carbide die, also known ascemented carbide punch rod or cemented carbide punch, mainly used for stamping hardwareparts or electronic parts, of course, can also punch other non-metallic parts,included belt holes, plastic holes and so on.Cemented carbide, also known as tungsten steel, is a sintered composite material consisting of multiple or one metalcarbide.Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide andtantalum carbide are common components of tungsten steel.The grainsize of the carbide component (or phase) is usually betwaeen 0.2 and 10microns, and the carbide grains are held together with a metal binder.Thebinder usually refers to the metal cobalt (CO), but for special purposes,nickel (Ni), iron (Fe), or other metals and alloys may also be used.The matrixof cemented carbide is composed of two parts: one is the hardening phase;The otherpart is the bonding metal.Bonding metal is generally iron group metal, commonlyused is cobalt, nickel.Thus there are tungsten-cobalt alloys, tungsten-nickel alloysand tungsten-titanium cobalt alloys.
