It is made of tungsten steel, which is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy.
Tungsten steel has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which remain basically unchanged even at a temperature of 500 °C. It still has high hardness at 1000℃.
