1. High density: The density of tungsten alloy is generally 16.5~19.0g/cm3, that is, more than twice the density of steel.
2. Good ductility: W-Ni-Fe high-density alloy has good ductility, its sintered state elongation can reach 10%~15%, after vacuum or atmosphere dehydrogenation treatment, elongation can be increased to 20%~30%.
3. Good electrical conductivity: W-Ni-Cu, W-Ni-Fe high-density alloy has good electrical conductivity, electrical corrosion resistance, high voltage resistance and other electrical properties.
4. High tensile strength: the tensile strength of sintered W-Ni-Fe high-density alloy is 800~1000MPa, and the strength can be increased to 1300~1500MPa after heat treatment and deformation processing.
5. Long service life: tungsten alloy wear resistance, corrosion resistance. With the progress of modern science, the storage protection technology of tungsten alloy has been further improved.
6. Low coefficient of thermal expansion: its linear expansion coefficient is only 1/2 to 1/3 of iron or steel. 7. Excellent radiation shielding ability: tungsten alloy plate has a higher density than lead plate, up to 18.8g/cm3, so its X-ray and gamma-ray absorption capacity is better than that of lead plate.
8. Good machining performance: Because W-Ni-Fe high-density alloy has good ductility, it can be machined, milling, planing, threading and tapping, and can also be rolled, rotary forging and forging processing and other large deformation strengthening treatment.
