Cemented carbide punch is a part of cemented carbide die, also called cemented carbide punch or cemented carbide punch. It is mainly used for punching hardware parts or electronic parts, of course, it can also punch other non-metals. Pieces, even belt holes, plastic holes, etc. Cemented carbide, also known as tungsten steel, refers to a sintered composite material composed of at least one metal carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, and tantalum carbide are common components of tungsten steel. The grain size of the carbide component (or phase) is usually between 0.2-10 microns, and the carbide grains are bonded together using a metal binder. The binder usually refers to the metal cobalt (Co), but for some special applications, nickel (Ni), iron (Fe), or other metals and alloys can also be used. The matrix of cemented carbide is composed of two parts: one part is the hardening phase; the other part is the bonding metal. The bonding metal is generally iron group metal, and cobalt and nickel are commonly used. So there are tungsten-cobalt alloys, tungsten-nickel alloys and tungsten-titanium-cobalt alloys
