Tungsten Carbide Die Description

Compared with conventional steel die, WC-Co tungsten carbide die has many advantages, such as high density, high hardness, high strength, low coefficient of thermal expansion, excellent wear and corrosion resistance and so on, whose service life is several times longer than the steel die. Common used tungsten carbide die grades are YG3, YG6, YG6X, YG8, YG15, YG20, YG20C, YG25, etc, and some non-magnetic alloy die materials. According to the different applications, tungsten carbide dies can be divided into tungsten carbide drawing die, cold heading die, non-magnetic die, thermal die, etc.

Tungsten carbide drawing die takes the major part and it plays an important role in metal processing by the external force is a pressure force by the metal mold, the metal cross-section is compressed so as to obtain a desired cross-sectional shape and size. Due to plastic and steel die has bad performance in wear resistance and service life, and although diamond drawing die has high hardness and wear resistance, it cost a lot. In summary, tungsten carbide drawing die has excellent properties and medium cost, which is the major part of drawing die materials; Cold heading die and stamping die are mounted on the respective use of machinery by applying a deforming force, the blank pre-formed. Carbide material hardness and excellent wear resistance, life million times in 5000-6000, the size does not substantially change, so as to effectively guarantee the dimensional accuracy of the product; No-magnetic alloy die generally used for the production of magnetic materials. Before non-magnetic tungsten carbide non-magnetic appearing, people has been using non-magnetic steel, mold its poor performance, low hardness and short life, the inner wall of the mold used for a period of time after a serious nap and deformation phenomena, so that the dimensional accuracy and surface quality of the magnetic material has been greatly affected. Non-magnetic carbide prepared by strictly controlling the carbon content and adding trace elements (Cr, Mo, Ta, NiB, Al, VC), which can replace the steel and improve the efficiency.
