Tungsten copper infiltration is to manufacture tungsten skeleton with density and strength, then filled in copper liquid under capillary force. And it can be divided into infiltrated Cu after high-temperature sintering skeleton and mix powder infiltration after low-temperature sintering.

Tungsten carbide powder is the intermediate in the line from W powder to cemented carbides. It can be produced from different raw materials and by different processes.

Tungsten copper properties combines the advantages of tungsten and copper, with micro-uniform structure, high temperature, high strength, resistance to arc ablation, density, conductivity, thermal conductivity and other high-quality properties.

Tungsten carbide button types are including conical buttons, wedge buttons, coal buttons, road buttons, flat buttons, claws buttons, spoon buttons and mushroom buttons.

China is a dominant country of tungsten resources and tungsten powder export, and export control conditions of 4xy3, has canceled export quota in 2016 and transferred to goods of export license administration.

Tungsten Carbide Rod Types

Tungsten carbide rod types including solid rod, single hole rod, double holes rod, double helix holes rod and triple helix holes rod.

Tungsten copper manufacture main methods are include copper infiltration, reduction, mechanical alloying, high temperature liquid phase sintering and activated liquid phase sintering. Our company is mainly use copper infiltration.

Tungsten crucible has many advantages which make it been widely used in rare earth smelting, quartz glass and crystal growth industries.
