Tungsten alloy fishing weight is a kind of fishing gear with counterweight which is made of tungsten, nickel, copper and other materials through powder metallurgy process, it has the advantages of small volume and big specific gravity. It can improve the efficiency of fishing and is favored  by the majority of anglers. Tungsten alloy fishing weights can be made into fish shaped fishing weight, due to its large density and small volume, compared with the lead and other materials, in the same weight, tungsten alloy fishing weight can dive deeper.
 
The advantages of tungsten alloy fish shaped fishing weights:
 
1. High density: its density is 2.5 times than the iron, 1.7 times than the lead, in the same weight, the volume is 30% smaller than the lead.
 
2. Strong wind resistance: tungsten alloy fishing weights have high density, and strong wind resistance, they are better than lead fishing weights in hand feel.
 
3. Corrosion resistance: tungsten alloy fish weights have chemical stability, and oxidation resistance, they have not the reaction with sea water, and they are also durable.
 
4. Hard material: the hardness of tungsten alloy fish weights is about 28HRC and they are removed easily, while the traditional lead fish weights are relatively soft, if they are swallowed by prey, they will not easily be removed.
 
5. Non - toxic: tungsten alloy is non-toxic and pollution-free, it has no effect on the environment and human health.
