Tungsten heavy alloy
Introduce: Description:
Tungsten alloys are materials with a high tungsten content and low amounts of Ni Fe or Ni Cu.
Advantages:
* High density (17.0~18.5g/cm3)
* Good machinability
* Good mechanical properties
* High modulus of elasticity
* High absorption capacity against χ-rays and γ-rays
* Harmless to the health and environment.
Applications:
* Protection shields for nuclear radiation
* Balancing weights
* Substitutional material for Uranium
* Electroheat upsetting anvil block
* Balls in bomb
* High voltage electrical contact
* Electrodes for Resistance Welding.
Product Standard: ASTM B 777 99
