Tungsten (W) is one of the so-called transition metals with the atomic number 74,it’s shiny gray metal in a solid state at room temperature.Tungsten has many outstanding characteristics,it has the highest melting point of all metal elements of 3422°C,and boiling point around 5,700°C closing to the surface temperature of Sun,thus it can withstand a very high temperature.With a high density of 19.3 g/cm³, closely to gold density,tungsten is widely used as balance weights for aircraft and helicopter.Tungsten is also resisted to various acid in room temperature,ever for hydrofluoric acid and aqua regia. 
Tungsten rod/bar/electrode is supplied by powder metallurgy method form tungsten powder to sintered tungsten bar,then after forging, rolling, swaging, and drawing processing singularly or in combination to reach the desired size.The finished appearance is black or silver according to different process method.

Application
Sintered Tungsten bar is mainly used for processing into tungsten wire and rod,while tungsten rod mainly used for producing ion implantation parts,electric light source, heating components in high temperature furnaces,and electrodes in the field of rare earth metal industry.

We also provide Tungsten Carbide Copper and Tungsten Carbide Silver.

Specification

Tungsten (W) is one of the so-called transition metals with the atomic number 74,it’s shiny gray metal in a solid state at room temperature.Tungsten has many outstanding characteristics,it has the highest melting point of all metal elements of 3422°C,and boiling point around 5,700°C closing to the surface temperature of Sun,thus it can withstand a very high temperature.With a high density of 19.3 g/cm3, closely to gold density,tungsten is widely used as balance weights for aircraft and helicopter.Tungsten is also resisted to various acid in room temperature,ever for hydrofluoric acid and aqua regia. 
During production process, the surface of tungsten wire was black coated with graphite, when graphite emulsion was removed,tungsten wire shows metallic luster. The surface of tungsten wire is free of burrs, cracks, scratches, pits, uneven, and oil.

Dimension and tolerance:

Application:

• Manufacturing electric light resource and electric vacuum parts;
• Heating element and fabricated components applied in high temperature;
• To manufacture tungsten spiral applied in the vacuum deposition 

Storage:

Tungsten wire should be kept in clear and dry place,with room temperature not higher than 28 ???, humidity less than 60%.It should be kept away from chemicals,cleaned wire should vacuum packaging to prevent surface oxidation.Tungsten materials are brittle at room temperature, do not vibrate or collision rapidly when moving.

Tungsten Crucible are characterized by high purity, high density, free of internal cracks, precise size and smooth inner and outer walls, was mainly used as the core container of  sapphire growth furnace,quartz glass melting furnace and rare earth blast  furnace.Especially for sapphire growth furnace,the tungsten crucible used have an big influence to the seed success rate, pulling quality control,crystal stick pan off and working life for sapphire crystal growing.
