2. High Strength
3. Strong Radiation Absorption Ability
4. Large Thermal Conductivity
5. Low Thermal Expansion Coefficient
6. Non-ferromagnetic
7. In addition, the tungsten-nickel-copper alloy has good conductivity, good weldability, and workability.
- Information
Tungsten-nickel alloy has a higher density (16.5-18.75g/cm3), higher strength (tensile strength of 700-1000Mpa), larger thermal conductivity (5 times of die steel), and smaller linear expansion Coefficient (only 1/2-1/3 of iron or steel), good electrical conductivity and plasticity, excellent weldability and machining performance.
Tungsten heavy alloys have many special properties such as high density (15.8-18.7g/cm3), high melting point, wear resistance, high tensile strength, good elongation capacity, low vapor pressure, excellent thermal stability and high radiation absorption capacity, etc. And due to these advantages, they are widely used in various fields including sports, industry, medicine, etc. The most common high-density Tungsten alloys are W-Ni-Fe and W-Ni-Cu.
Applications：
In view of the above-mentioned excellent properties of tungsten-nickel-copper high specific gravity alloy, it is widely used in aerospace, aviation, military, oil drilling, medicine, and other fields.
In addition, because such alloys are non-ferromagnetic and have relatively good electrical and thermal conductivity, they are often used in occasions with special requirements, such as gyroscope rotor and other parts and components of devices and instruments that require working under the magnetic field, and the electrical contacts of high-voltage electrical switches and some electrodes for electrical processing.
