Tungsten Alloy Screw For Spare Parts
Heavy Tungsten Alloy Screw is kind of heavy tungsten alloys because they are more than twice as heavy as steel. High specific gravity tungsten alloys are usually refractory metals containing W-nickel-iron, W-nickel-copper, or even W-nickel-copper-iron complexes. Some tungsten alloys have rare earths and/or other metals such as cobalt, molybdenum, and chromium added. Heavy tungsten alloy has a high melting point, twice the density of steel, and is more than 50% heavier than lead.

High density: The density of tungsten alloy is 18.5g/cm3, which is much smaller than other materials of the same mass.
Corrosion resistance: The chemical properties of tungsten alloys are stable and will not react with any substances at room temperature. If it is iron, it is easily oxidized.
High hardness: The hardness of tungsten alloy is second only to diamond, and the hardness is quite high. The fishing extender will inevitably collide with hard objects during use. The high hardness material can make the salvage countersunk head not easy to break and deform.
