Tungsten pin

Tungsten pin

Tungsten pin is pin made of the material—tungsten. Since it is made of tungsten, tungsten pin owns the properties of high melting point, high corrosion resistance, tensile strength and low coefficient of thermal expansion. When added steel or other element, its hardability would be improved. 

The surface condition of tungsten pin is smooth and bright. Moreover, no stain, dirt, oxides, drawing tracks, scratches and damages are admitted on the surface of tungsten pin.
  

Tungsten Needle

Tungsten Needle

Tungsten needle is widely used in the construction of furnace tooling and parts and as a feedstock for the fabrication of parts for the electronics and semiconductor industries. Surface can be supplied in a shiny or matte; dependent upon the thickness and width parameters. 

Tungsten needles grown from hexacarbonyl tungsten vapors in a glow-discharge condition are described. The needle growth occurs on a tungsten substrate in a temperature range from nearly room temperature to 1500 °K, but needles produced below and above ~1100 °K are quite different in morphology and crystalline state. The products at lower temperatures are tungsten particles agglomerated in dendrite like shapes while those at higher temperatures possibly are whiskers.
