Tungsten alloy has high strength and toughness, good heat resistance, corrosion resistance, especially high hardness and wear resistance. At present, professional dart players use tungsten alloy darts, which are made of tungsten alloy dart barrel.

Tungsten alloy dart shaft main material is hard metals, so it has high hardness, high-temperature corrosion resistance of hard metals. Other precious metal pastes make tungsten alloy dart shafts have higher hardness. Because of the precious metal pastes, tungsten alloy dart shafts production process is more complex than other hard metals. 

 

 

Tungsten alloy dart shaft making needs milling, just like other hard metal. The prepared powder can be mixed only after a strict formula of wet grinding. The mixture also needs to be pulverized, dried and sieved. After these, tungsten alloy dart powder is done. The next is the molding process. It is necessary to add a molding agent into the powder and then dry it again to remove the residual moisture in the powder. Making the sifted mixture into particles, then it’s the low pressure sintering time, finally, the billet of tungsten alloy dart shaft is complete. 

 

Tungsten alloy dart shaft billet needs to have the flaw detection. If it’s the fine tungsten alloy dart shaft, it has outer circle grinding process after the inspection. If it’s ordinary tungsten alloy dart shaft billet, this process can be omitted. Then it needs to check the size after detection. Only qualified tungsten alloy dart shaft can be packaged and stored. 

 

At present, the domestic tungsten steel dart rod adopts the world advanced production process. Its the unique technology of low pressure sintering can ensure the products has high hardness and wear resistance. Advanced production technology can make the tungsten dart porosity reduced to improve the compactness of the products in the final sintering stage.

 

Tungsten alloy dart shaft is the standard material for making dart barrel. It has large density, good air power effect, and small volume, which increases the possibility of throwing darts into the same partition.
