1. High density
Density is the mass per unit volume of a substance. It is a characteristic of a substance and is only related to the type of substance and has nothing to do with the mass or volume of the substance. The density of tungsten alloy is generally 16.5~19.0g/cm3, which is equivalent to more than twice the density of steel. Generally, the higher the tungsten content or the lower the bonding metal content, the higher the density of the tungsten alloy; conversely, the lower the density of the alloy.

2. High melting point
Melting point is the temperature at which a substance changes from solid to liquid under a certain pressure. Tungsten alloy has a higher melting point, about 3400°C. This means that the alloy material has better heat resistance and is not easy to melt.

3.High hardness
Hardness refers to the material's ability to resist denting and deformation caused by the intrusion of other hard objects. It is one of the important indicators of the wear resistance of the material. The hardness of tungsten alloy is generally 24~35HRC. Generally, the higher the tungsten content or the lower the bonding metal content, the greater the hardness of the tungsten alloy and the better the wear resistance; conversely, the smaller the hardness of the alloy, the worse the wear resistance.
