Copper tungsten alloy (W-Cu) is the composite of tungsten and copper which own it excellent performance of tungsten and copper.
Copper tungsten may be used as an electrical contact material. In the most severe applications associated with power generation and transmission the switch may be totally immersed in oil. In these cases there is no advantage in using the tarnish resistant silver-based materials, as oxidation is prevented by the exclusion of air. Copper tungsten contacts are widely used in these cases, the selection of the grade used being dependent on the relative importance of conductivity and arc resistance.

A combination of the advantages of tungsten and copper, high temperature resistance, electric arc ablation, high intensity, than the major, conductive, thermal conductivity, and ease of machining, and it has features such as cold sweating, as with tungsten high hardness, high melting point, anti-adhesion characteristics, often used to do a certain resistance to abrasion, resistant to high temperature welding, butt welding electrode.
Silver tungsten materials are used in industrial and domestic circuit breaker applications where good weld and erosion resistance is important. Various grades are available: - the higher silver grades have higher conductivity, and the higher tungsten grades have greater erosion and weld resistance.
Tungsten heavy alloy generally are refractory metal, which have two-phase composites consisting of W-Ni-Fe or W-Ni-Cu or even W-Ni-Cu-Fe, some tungsten alloy is added Co, Mo, Cr, etc. It could be made as various shapes, such as rod, cube, block, brick, ring, etc.
Bucking bar is a work tool received behind work surfaces to provide a backing member in applying impact fasteners and including intermitted tool head and handle parts with a low-recoil impact-absorbing spacer provided there between to take shock loads in compression and shear.
Tungsten is the most widely used of the refractory metals. In wire form, it is essential for the production of lighting products such as wire filament, and other goods where its high temperature properties are of use. Among its properties are a melting point of 3410° C, a low coefficient of thermal expansion and low vapor pressure at elevated temperatures, along with good electrical and thermal conductivity.
Molybdenum material are used in the following industries: glass melting, vacuum furnace, vacuum deposition, aerospace, solar,nuclear, electronics,automotive, and medical.
We carry molybdenum in wire, rod, sheet, and plate. We also sellmolybdenum nuts, bolts, heat shields, and other hardware for vacuumfurnace and high vacuum environments.
