What is Tungsten Alloy Counter Sunk?
High specific gravity tungsten alloy with high density, high strength, high hardness (commonly known as 3H alloy) and good ductility, electrical conductivity and thermal conductivity and other comprehensive excellent performance, in weapon manufacturing, national defense construction plays an important role. 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.
Tungsten alloys are also known as tungsten heavy alloys because they weigh more than twice as much as iron or steel. High specific gravity tungsten alloys are usually refractory metals composed of tungsten nickel-iron or tungsten nickel-copper or even tungsten nickel-copper iron two-phase complex. Some tungsten alloys add rare earth and/or other metals, such as cobalt, molybdenum and chromium. Tungsten heavy alloys have a very high melting point, density is twice that of steel, and it is more than 50% heavier than lead.
Application of Tungsten Alloy Counter Sunk
- Tungsten alloy counter sunk is a kind of tungsten alloy material production of fishing gear. Tungsten alloy fishing pendant has high density, small volume and different shapes, suitable for various river sections. Tungsten alloy fish pendant can be divided into worm-shaped fish pendant, barrel-mounted fish pendant, needle-shaped fish pendant, bullet-shaped fish pendant, teardrop-shaped fish pendant and so on.
