Inspired from powder injection molding of conventional powder metallurgy (PM), tungsten-copper composite powder injection molding technology is based on the injection of tungsten skeleton is formed, and it breaks the limitations of conventional Infiltration produced tungsten-copper composite. Metal injection molding (MIM) is a kind of process that suitable for fabricating the products with complex or irregular shape, and it was first extended by the plastic injection molding industry. In recent years, a substantial increase in the content of the solid…

Tungsten copper (W-Cu) and molybdenum copper (Mo-Cu) are composed of respectively tungsten and molybdenum with copper, which called two-phase composites and has many advantages when it used in some devices with high power, such as high hardness, high strength, high melting point, excellent chemical stability, excellent thermal and electrical conductivity and lower coefficient of thermal expansion. As a kind of electronic packaging heat sink material takes place of conventional materials gradually, the related researchers make an intensive study on tungsten…

Except the granularity of tungsten powder, copper (Cu) content also has an influence on the comprehensive properties of tungsten copper electrode. There is product with different copper content by two kinds of infiltration process (Conventional infiltration CV, Microwave infiltration MW) comparison: The table to compare the performance of tungsten copper alloy electrodes by different proportions of the product relative density, electrical conductivity and Brinell hardness (HB) and several parameters under different infiltration process. View from the sheet, we can easily…
