Heavy Tungsten Alloy Sinker Picture:

What is Heavy Tungsten Alloy Sinker?

Heavy tungsten alloy sinker has high density, high strength, high hardness (commonly known as 3H alloy) and good ductility, electrical conductivity and thermal conductivity and other comprehensive excellent properties. It plays an important role in weapon manufacturing and national defense construction. High specific gravity tungsten alloy materials have been widely used in industry, aerospace and civil industry (such as electrical industry, drilling industry, etc.), and become a popular dual-use alloy materials.


Tungsten alloys are also known as tungsten alloys because they weigh more than twice as much as steel. High specific gravity tungsten alloys are usually refractory metals composed of wNFE-Fe or WNNI-Cu or even WNNI-cu-Fe. Some tungsten alloys add rare earths and/or other metals, such as cobalt, molybdenum and chromium. Heavy tungsten alloys have a high melting point, are twice as dense as steel and more than 50 percent heavier than lead.


Application of Heavy Tungsten Alloy Sinker

  • Heavy tungsten alloy sinker is a kind of tungsten alloy material made of fishing gear. Tungsten alloy fishing pendant has the advantages of high density, small volume and diverse shapes. Suitable for various river sections. Tungsten goldfish pendant can be divided into insect shaped fish pendant, bucket shaped fish pendant, needle shaped fish pendant, bullet shaped fish pendant, water drop shaped fish pendant and so on.
