Tungsten-nickel-copper alloy for 93WNiCu ray shield protection

Tungsten-nickel-copper alloy refers to a kind of important tungsten based heavy alloy, which is composed of nickel and copper added to tungsten and other metal elements added on this basis. The ratio of nickel to copper is usually 3:2. This kind of alloy ferromagnetic, conductive and thermal conductivity is relatively good, often used in some special requirements of the occasion, such as gyroscope rotor and other requirements under the action of the magnetic field of the device and instrument parts; High - voltage electrical switch contact and some electrical processing electrodes.

The ratio of nickel to copper (by weight) is generally 3:2. Compared with tungsten-nickel-iron alloy, because copper does not have the effect of nickel and iron activation sintering tungsten, its sintering density is slightly lower, strength and plasticity is poor, generally do not carry on heat treatment and deformation processing. This kind of alloy ferromagnetic, conductive and thermal conductivity is relatively good, often used in some special requirements of the occasion, such as gyroscope rotor and other requirements under the action of the magnetic field of the device and instrument parts; High - voltage electrical switch contact and some electrical processing electrodes.

Physical characteristics of 93WNiCu tungsten nickel-copper alloy:

Specific gravity: general specific gravity is 16.5 ~ 18.75g/cucm;

High strength: tensile strength of 700 ~ 1000MPa;

High thermal conductivity: 5 times that of die steel;

Small thermal expansion coefficient: only iron or steel 1/2 ~ 1/3, good conductivity; It has good weldability and workability
