Tungstene Metal Powder

Descripción del producto

As pure metal, tungsten has not only the highest melting point of all metals (3,**2°C) and the lowest degree of thermal expansion, but it is also very dense (*9.3 g/cm³), has a high degree of mechanical strength and rigidity and very low vapor pressure.Due to these and other outstanding properties, tungsten is indispensable in many key industries. Its high density, mechanical attenuation properties, high capability for absorption of ionizing radiation and ease of mechanical processing are used to their best advantage in tungsten heavy metal alloys based on: tungsten-nickel-iron (W-Ni-Fe), tungsten-nickel-cobalt (W-Ni-Co) and tungsten-nickel-copper (W-Ni-Cu). These alloys are used as mass balancing weights and attenuators in aircraft construction, in motors and power trains, as oscillating weights and centrifugal weights in machines and in equipment construction, and in medical technology for both protection from and focusing of ionizing radiation in x-ray and measuring devices.

The high degree of thermal resistance in combination with very good thermal and electrical conductivity of tungsten-copper materials makes them particularly suitable for applications in high performance electrical switch contacts, as heat sinks in the electronic industry and as erosion electrodes.In the coatings industry, pure tungsten is used as a crucible material and for sputtering targets; in high temperature furnace construction it is used in heating equipment and thermal protection.
