Tungsten heavy alloy cylinder

Tungsten heavy alloys generally are refractory metal, which have two-phase composites consisting of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe, some tungsten alloy is added with Co、 Mo、Cr, etc. They have very high melting point and have a density twice that of steel and are more than 50% heavier than lead. Tungsten content in conventional heavy alloys varies from 90 to 98 weight percent and is the reason for their high density (between 16.5 and 18.75 g/m3). Nickel, iron and copper serve as a binder matrix, which holds the brittle tungsten grains together and which makes the alloys ductile and easy to machine. Nickel-iron is the most popular additive, in a ratio  of 7Ni:3Fe or 8Ni:2Fe (weight ratio). The conventional processing route for tungsten heavy alloys includes mixing the desired amount of elemental powders, followed by cold pressing and liquid phase sintering to demanded density. The matrix alloy melts and takes some tungsten into solution during liquid phase processing, resulting in a microstructure through which large tungsten grains (20–60µm) are dispersed in the matrix alloy. The as-sintered material often is subjected to thermo mechanical processing by swaging and aging, which results in increased strength and hardness in the heavy alloys. Tunsten Alloy Tip Counterweight 15.8-18.5 g/cm3

Tungsten alloy tip is small in volume and very dense, which means it can be used in all fields that are using small but heavy parts. Tungsten heavy alloy tip can be used as extremely precise counterweight for racecars, boats, yachts; sailboats, airplanes, helicopters, rockets,  tanks,  Precision instrument fields can also benefit from our tungsten heavy alloy tips. It is also largely used in mobile phone vibrator, clock cube, self-winding watches, anti-vibration toll holders, flywheel weights, etc. 85-97% W-Ni-Fe W-Ni-Cu Tungsten Alloy Fitting
