Tungsten alloy tip is in small volume with high density, which means tungsten alloy tip could be used in some fields need the little but heavy parts, such as counterweights for racing car, boat, yacht; sailboat, airplane, helicopter, racket, tank, etc. especially, some fields concerning with precision instrument, such as mobile phone tungsten alloy vibrator, clock cube, self-winding watches, anti-vibration toll holders, flywheel weights, etc.
-
Tungsten heavy alloy is usually consisted of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy is added Co¡¢Mo¡¢Cr, etc. It could be made as many shapes. Tungsten heavy alloy tubes is usually used in making radiation shielding, some parts for military defence, such counterweights for hunting guns, hunting equipment, the missile weapons, armor piercing ammunitio, counterweights for oil logging, etc.

Tungsten alloy(heavy alloy) is ideal for shielding against X rays and gamma radiation. The very high density of tungsten shielding (more than 60% denser than lead) allows a reduction in the physical size of shielding components, without compromising their rigidity or the effectiveness of the shielding characteristics. Tungsten alloy radiation shielding is used in applications such as collimator, nuclear shielding, beamstop, PET syringe shield, vial shield, isotope container, FDG container, multi leaf collimator etc.

There are three types of tungsten balls–pure tungsten ball, tungsten alloy ball and tungsten carbide ball.
Pure tungsten ball has the highest density among tungten balls, which iis over 19.2g/cm3. Pure tungsten ball also has the highest melting pointing. -
Tungsten boat/crucible is mainly used in metallurgical industry, machinery processing, glass and ceramic industries, as well as containers for coating materials
-
A tungsten contact disc is treated by burnishing, so as to smooth and compact the contact surface and remove the surface-crazed metals and oxides, while simultaneously filling the surface pores with a contaminant such as iron. The contaminants present in the pores are subsequently removed by immersing the contact disc in a dissolving agent, and the remaining natural oxides of the tungsten are removed from the walls of the pores by cathodic reduction, to create large pore sites, which are free of oxides and contaminants.
-
This refractory metal composite materials are a combination of tungsten combined with copper or silver. The manufacturing process is to press the refractory, sinter the pressed compact at a high temperature, and infiltrate with copper or silver. All this is done under very closely controlled conditions. The result is a relatively hard materials with superior arc and wear resistance, high physical properties at elevated temperatures, and good electrical and thermal conductivity.
