What is Tungsten Alloy Fishing Sinker?

  1. High specific gravity tungsten alloy has high density, high strength, high hardness (commonly known as 3H alloy) and good ductility, electrical conductivity, thermal conductivity and other comprehensive properties, which play an important role in weapon manufacturing and national defense construction. It has been widely used in industry, aerospace and civil industry (such as electrical industry, drilling industry, etc.), high specific gravity tungsten alloy material has become a kind of dual-use alloy material attracting much attention.
  2. Tungsten alloys are also known as heavy tungsten alloys because they weigh more than twice as much as iron or steel. High specific gravity tungsten alloys are usually refractory metals composed of wN-Ni - Fe or WN-NI - Cu or even WN-Ni - Cu - Fe complexes. Rare earths and/or other metals such as cobalt, molybdenum and chromium are added to some tungsten alloys. Heavy tungsten alloys have a high melting point, are twice as dense as steel and more than 50 percent heavier than lead.


Application of Tungsten Alloy Fishing Sinker

  • Tungsten alloy fishing sinker is a kind of tungsten alloy material production of fishing tackle. Tungsten alloy fishing pendants have high density, small volume and different shapes, which are suitable for different river sections. Tungsten alloy hook can be divided into worm hook, barrel hook, needle hook, bullet hook, teardrop hook and so on.
