The high swelling component is limited by the surrounding second component, and the powder is sintered in a lower temperature and wet. According to relevant experts, because the physical properties of metal copper and tungsten are quite different, the melting and casting method cannot be used for processing. The production method is to mix nickel powder, copper tungsten powder or iron powder with a uniform particle size of 15 microns, tungsten powder with a particle size of 0. The patented technology of a US company is copper oxide powder (mixed and ground to restore copper) instead of metal copper powder.Introduce you to the production skills of Tape for copper foil tungsten-copper alloy. According to reports, the selection of very fine powder can improve the sintering function and densification, making it more than 99%. The use of this technology in industry has achieved great success, with low cost and high yield, and the processed components reach the net shape and close to the net shape. The technical process of using powder metallurgy to prepare tungsten-copper alloys is the mixing of powdered ingredients, limiting forming, sintering, infiltration and cooling. Copper forms a continuous matrix in the sintered compact, and tungsten serves as a strengthening framework..Nowadays, powder alloy technology is generally used for processing.52 microns and tungsten powder with a particle size of 515 microns, and then mix with 25% 30% organic adhesive ( Such as white wax or polymethyl vinegar) injection molding, steam cleaning and irradiation to remove the binder, sintering in the middle to obtain high-density tungsten alloy. Tungsten-copper composite material is a two-phase structure pseudo alloy mainly composed of tungsten and copper elements, and is a metal matrix composite material. Japan's Sumitomo Electric Company chose injection molding to make a high-density tungsten alloy
