Ready to press tungsten powder is a kind of powder used for cemented carbide sintering. It has excellent physical and chemical properties, good fluidity and compressibility, high chemical content and good carbon control.
Characteristics
Ready to press tungsten powder has stable apparent density, good liquidity and compressibility. Its chemical content is high, and amount of carbon control is good.
Applications
Ready to press tungsten powder is a raw material sintered in cemented carbide. During sintering, a series of physicochemical processes such as diffusion, recrystallization, fusion welding, compounding, dissolving among powder particles, it become a cemented carbide which has a certain porosity.
Cemented carbide is a powder metallurgy product mainly made of carbide micron-sized powder of high-hardness refractory metal and sintered in vacuum furnace or hydrogen reduction furnace with cobalt or nickel and molybdenum as binder.
