With an acknowledged fame as one of the Chinese most experienced and professional tungsten products manufacturer, we Kefeng manufactures tungsten alloy parts and components to the superior specifications and quality standards, for which the process is ISO9001 certified and materials are SGS approved.
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
The heavy tungsten alloy material possess the highest melting point of all metals and suitable for very high-temperature applications. It is also characterized by a uniquely low coefficient of thermal expansion and a very high level of dimensional stability.
- High temperature resistance
- High impact and crack resistance
- Shock and corrosion resistance
- Good modulus of elasticity and high hardness
Application
These High Density Tungsten Heavy Alloy Components are twice as heavy as steel and more than 50% heavier than lead, they have become an essential material for a wide variety of applications in aerospace, defense, medical, and oil and gas exploration.
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.
