CuAl2O3 Inlaid Tungsten Electrode
CuAl2O3 inlaid tungsten electrodes, which combine the benefits of both tungsten and CuAl2O3, are composite. With the inlay procedure, CuAl2O3 is mixed with tungsten components optimized for various applications. CuAl2O3 is a composite material with a copper matrix and dispersed particles of aluminum oxide. It has remarkable attributes, such as excellent electrical conductivity (≥85% IACS), high hardness (>HRB 84), and high softening temperature (≥900℃). It also has good ablation resistance and excellent heat dissipation properties. Additionally, tungsten has a high melting point, is chemically stable, and is also high in hardness. The inlay method synergistically combines the microstructural wear resistance and high temperature attributes of tungsten with the electrical and thermal conductivity of CuAl2O3. The manufacture of this electrode typically utilizes powder metallurgy, which has as one of its phases the high-pressure molding and sintering at high temperatures. This procedure is used to achieve CuAl2O3 material densification and to inlay the tungsten components. This also guarantees interfacial bonding, a homogeneous microstructure, and a uniform structure, commensurate with the electrode's stability during use.
