Tungsten heavy metal is the raw material of making tungsten heavy metal pins, so tungsten heavy metal pins have the properties of high melting point, low vapor pressure, high corrosion resistance, and tensile strength and low coefficient of thermal expansion. The surface condition of pure tungsten heavy metal pin is smooth and bright. Moreover, no stain, dirt, oxides, drawing tracks, scratches and damages are admitted on the surface of tungsten pin. Tungsten heavy metal pin is widely used as vise, electrodes, fishing sinker and microsurgical.

Tungsten heavy metal pin with great hardness can be used as vise. Tungsten heavy metal pin vise, with a wide choice of micro tungsten heavy metal pin, is ideally suitable for probing, picking, scribing, cleaning, marking and similar fine work. There is a wide choice of fine pointed pins for different grades of precision work.

Compared to darts pin made of copper and brass, tungsten heavy metal dart pin gives experienced dart players the designed weight with slimmer appearance.

Tungsten heavy metal pin is also used to make electrode of flash lamp in camera, sodium lamps, halogen lamps, metal halide lamps owing to high strength at high temperatures of tungsten. Tungsten heavy metal electrode pin contains 99.50 percent tungsten heavy metal, having the highest consumption rate of all electrodes and typically are less expensive than their alloyed counterparts.
