Special and Customized Tungsten heavy metal alloy 92.5WNicu ring
The features of the tungsten heavy alloy ring:
1. The high desity with the small volume
2. The high melting point
3. The excellent hardness
4. The superior wearing resistance
5. The high ultimate tensile strength
6. The high ductility
7. The wonderful machinability
8. The high impact resistance and crack resistance
9. The non-toxic and friendly-environment characteristics
Tungsten material is widely used for tungsten heavy rings. They work as so-called tungsten rings in many fields, such as racing car, yacht, airplane and so on. Density of tungsten alloy could be ranged from 17.0g/cm3 to 18.5g/cm3. And the capacity could be reduced if it needs to be use in a small place. Besides, as its special properties, such as high hardness, wearing résistance, excellent elongation, well machining ability, it is a suitable material for counterweight for airplane.
The tungsten heavy alloy rings have the high density, which is up to 18.5g/cm3. The mechanical properties can suit either dynamic or static locations. They are non-magnetic and non-toxic. They are safe and environmentally friendly. The tungsten heavy alloy has the great resistance to the corrosion. They can easilu mechanically joined, brazed or shrunk fit to other materials.
