Tungsten Based High Density Alloys are materials with a high tungsten content and low amounts of NiFe or NiCu.
Advantages:
1.High density
2. Good machinability
3. High modulus of elasticity
4. High absorption capacity against x-rays and Υ-rays
4. High absorption capacity against x-rays and Υ-rays
5. Harmless to the health and environment
6. Good mechanical properties
Applications:
1 Protection shields for nuclear radiation
2. Balancing weights
3. The war industry with the ball core, the ball link, the shrapnel, the aemor-piercing shell uses the ball
4 Substitutional material for Uranium
5Electroheat upetting anvil block
6 High voltage electrical contact
7 Electrodes for Resistance Welding
