The applications of Tungsten powder

The applications of Tungsten powder
 
Most of tungsten powder is used to produce cemented carbide and tungsten iron. Tungsten and chromium, molybdenum and cobalt are used to form heat-resistant and wear-resistant alloys for the production of tools, metal surface hardening materials, gas turbine blades and combustion tubes.

Tungsten and bismuth, antimony, molybdenum and other refractory alloys. Tungsten copper and tungsten silver alloys are used as electrical contact materials. A high-density tungsten-nickel-copper alloy is used as a radiation protection shield. Wires, rods, sheets, etc. of metal tungsten are used to make electric bulbs, components of the tubes, and electrodes for arc welding.

Tungsten powder can be sintered into filters of various porosity. FW-1 is used for large slab and tungsten-rhenium galvanic materials. FW-2 is used for contact alloys and high specific gravity shielding materials. FWP-1 is used for plasma spray materials.

Tungsten powder is the main raw material for processing powder metallurgy tungsten products and tungsten alloys. Pure tungsten powder can be made into processed materials such as silk, rods, tubes and plates, and certain shaped products. Tungsten powder is mixed with other metal powders to form various tungsten alloys such as tungsten-molybdenum alloy, tungsten-rhenium alloy, tungsten-copper alloy and high-density tungsten alloy. Another important application of tungsten powder is the production of tungsten carbide powder to produce cemented carbide tools such as turning tools, milling cutters, drill bits and molds.
