Characteristics of tungsten alloy:

1. High density: The density of tungsten alloy ranges from 17-18.6g/cm3, which is more than twice the density of steel. Therefore, tungsten alloy is an alternative material to replace steel in applications that require small volume and heavy weight.

2. High tensile strength: The tensile strength of sintered tungsten alloy is 800-1000MPa, and the strength can be increased to 1300-1500MPa after heat treatment and deformation treatment.

3. Good elongation: The elongation of sintered tungsten alloy is 10%-15%, and the elongation can be increased to 20%-30% after vacuum or atmosphere dehydrogenation.

4. Good radiation absorption ability: Tungsten alloy has a radiation absorption ability that is 30-40% higher than lead, and there is no pollution.

5. Good machining performance: Compared with pure tungsten, tungsten alloy has good processing performance and can be processed in various ways, including turning, milling, planing, threading and tapping.

Application of tungsten alloy:

The following are common applications of tungsten heavy alloy (WHA):

1. Collimators, shielding parts, etc. for medical and industrial X-ray equipment

2. Radiation shielding cans, syringe protective sleeves, etc. for gamma ray equipment and isotope containers

3. Various balance blocks, crankshaft counterweights and rotors for aircraft and racing cars

4. Tungsten alloy boring bars and sleeves for internal hole cutting

5. Die parts, core pins and sleeves for die casting

6. Counterweights for the oil industry and golf clubs, etc.

7. Electric heating roughing molds in heat treatment

8. Dart shafts
