Tungsten Alloy Cubes Fragments for Industry and Military AMS-T-21014 and ASTM-B-777
Product Description
Military tungsten alloy cube refers is made by a metal compression molding process. It has good physical and chemical properties. There are basically two series, W-Ni-Fe and W-Ni-Cu. It mainly contains 90%-97% tungsten, and the density can reach 16.85-18.8g/cm3. Nickel, iron, and copper act as a binder between tungsten particles, making the material malleable and workable. Compared with W-Ni-Cu, W-Ni-Fe has better mechanical properties and is widely used in the national defense industry. W alloy military cubes are part of the W-Ni-Fe series. Due to its high hardness and high-temperature resistance, it is now increasingly used in military defenses.
We look forward to the opportunity to work with our customers and we'd like to create personalized specifications. Flexibility is our strength, and our mission is to meet customer needs.
Characteristics and features
1. High temperature resistance
2. High impact and crack resistance
3. Shock and corrosion resistance
4. High absorption capacity against X-rays and gamma
5. Good modulus of elasticity and high hardness
Application
As tungsten alloy cubes are small volume with high density, so it can be used in some fields needing the little but heavy parts, like the counter weights of golf club, pinewood derby car, aircraft, helicopter, vehicle, boat and yacht, especially in precision instrument fields: mobile phone vibrator, clock cube, self-winding watches, anti-vibration toll holders, flywheel weights.
