SPECIFICATION

Tungsten

Tungsten is an irreplaceable material in a wide range of industries and applications including quartz glass, health care, coating processes, thermal processes and ion implantation. Tungsten has the highest melting point and lowest vapor pressure among all the refectory metals. The high strength and thermal coefficient in extremely high temperature conditions makes tungsten very suitable for fabricating high temperature furnace parts, heating elements and arc-welding electrodes.

Machinable tungsten metal and alloys have been used extensively for furnace parts manufacturing due to its very high melting point and low vapor pressure. The high chemical purity and homogeneity of tungsten also makes it an ideal material for producing sputtering targets and vapor evaporation. The ability of high density machinable tungsten to absorb radiation and resist corrosion is invaluable when tungsten is utilized as a radiation shielding material.

Tungsten Furnace Components

Heating elements and shields in furnaces which are machined from tungsten rod, sheet and wire retain these excellent properties. Meanwhile tungsten furnace parts can maintain a high level of chemical stability, corrosion resistance and strength throughout a long service life.

Therefore, tungsten machined furnace assemblies and parts are an ideal choice for users of various high temperature furnaces including hot isostatic pressing (HIP) furnace, crystal growth furnace, sintering furnace, vacuum furnace.
