MILT Tungsten Heavy Alloy Cubes 3.0mm to 10mm Heavy Metal For Weight Balancing
As tungsten heavy alloy cubes are high density with small capacity, high temperature resistance, high impact resistance and crack resistance, wonderful shock resistance, good corrosion resistance, High absorption capacity against X-rays and gamma rays, Good modulus of elasticity, High hardness, etc.
The first tungsten heavy alloy developed was a W-Ni-Cu alloy. Alloys of this ternary system are still occasionally used today, primarily for applications in which ferromagnetic character and electrical properties must be minimized. W-Ni-Cu alloys otherwise offer inferior corrosion resistance and lower mechanical properties than the present industry standard W-Ni-Fe alloys.
High density tungsten alloy cube has excellent radiation resistance, electric and thermal conductibities and corrosion resistance characters with high density (16---18.5g/cm3) and good mechanical strength. It has small coefficient of expansion and large elastic modulus. Tungsten heavy alloy cube is extensively used in military equipment, mechanical manufacturing, aircraft components, medical shields and sports equipment.
Tungsten Heavy Alloy Cubes Advantages:
Tungsten alloy cubes is in small volume with high density, which means it could be used in some fields need the little but heavy parts, such as the counterweights of golf club, Pinewood Derby car, aircraft, helicopter, vehicle, boat and yacht;
Especially in precision instrument fields, such as mobile phone vibrator, clock cube, self-winding watches, anti-vibration toll holders, flywheel weights, etc.
