Tungsten Heavy Alloy Products 

           Symbol: W + Ni/Fe, W + Ni/Cu

           Technology: Max powder --> pressing --> sintering --> tooling

           Tungsten heavy alloy have excellent radiation resistance, electric and thermal conductivities ( 0.2--0.3CGS ) and corrosion  resistance with high density ( 16.4 --18.5 g/cm3 ) and good mechanical strength. It has small coefficient of expansion and large elastic modulus. Tungsten products are extensively used in military equipment, nuclear, mechanical manufacturing, aircraft components, medical shields and sports equipment.

            We supply tungsten alloy products such as W-Ni-Fe and W-Ni-Cu. The products are vary in shape from rod,  ball,  ring block strip to abnormal pieces according to the user's request (see table 3) . All of our tungsten alloy products are up to the grade of AMS-T-21014 (see table 1,2).  We can provide other types and sizes tungsten alloy products with varying contents and  properties.
