Copper Sintering Of Superfine Tungsten Copper Powders
One of the key components in the production of electrical vehicles is batteries. Cobalt and lithium are two main minerals used in the production of electric vehicle batteries. Lithium in particular is a critical component in the production of the lithium-ion batteries needed to produce electric vehicles. Interestingly, some of the world’s largest lithium reserves are found in Mexico.
On the other hand, wind turbines rely on a number of critical minerals, including cobalt, copper, manganese and nickel. Under the 2 degrees Celsius climate scenario, a 250 percent rise in demand is expected for key minerals used in wind turbines, including aluminum, chromium, copper, iron, lead, manganese, molybdenum, neodymium, nickel and zinc.
Although both tungsten and copper have a good wetting ability, they differ vastly in physical properties and cannot form alloy by solid solution with each other. Therefore, through the direct tungsten copper sintering in the usual conditions, it is impossible to obtain high-density products. The sintering temperature exceeds the melting point of copper. The liquid-phase tungsten copper sintering occurs. Due to the development of superfine powders mixed sintering, tungsten copper composites with various components have been directly produced through molding and sintering superfine tungsten copper mixed powder. The powder was obtained from the co-reduction of the superfine tungsten-copper mixed.
Tungsten Copper composite with high skeleton density
Tungsten Copper sintering can adjust and control the particle size of raw material tungsten powder and the system of high-temperature sintering. The required tungsten copper composites were obtained via copper infiltration. High-temperature tungsten skeleton sintering and copper infiltration can remove the impurities in the materials to the maximum extent. The low gas content and the sintered Tungsten skeleton with high strength ensure the excellent strength performance of Tungsten Copper composites.
