High density : 18.1- 18.5 g/cc  
High melting point: about 3410 °c
High ultimate tensile strength    
High ductility 
High-temperature resistance 
Low vapor pressure
Small volume: Even though the weight is higher, its volume is smaller than conventional lead fishing plummet, which makes it not easy to be found by fish. You could fish easily even in the deep-sea area.
Excellent hardness: Conventional fishing sinkers is so soft that it is always stuck in the throat of fish and difficult to remove it. after they swallow it. This problem could be solved based on the high hardness of tungsten alloy fishing weights.
Superior wearing resistance: The fishing experience will be much better with a higher hook rate caz of the high density and wind resistance.
