WNiFe Heavy Tungsten Fishing Weights Beads For Fly Tying Counter Sunk

Tungsten Fishing Weights are a kind of tungsten based alloy (generally 80% ~ 98% tungsten content). Small amounts of nickel, iron, copper, cobalt, molybdenum, chromium and other elements are added to the alloy material. The density of high specific gravity tungsten alloy is up to 15.20~18.70 g/cm3, also known as heavy tungsten alloy or high density alloy material. Because tungsten alloys weigh more than twice as much as iron or steel.

What is Tungsten Fishing Beads?

Tungsten alloy has a series of excellent properties, significant ratio: general ratio of 16.5-18.75g/cm3, high strength: tensile strength of 700-1000mpa, strong ray absorption capacity: 30-40% higher than lead, large thermal conductivity: 5 times of die steel; Low thermal expansion coefficient: only 1/2-1/3 of steel, good electrical conductivity; Good weldability and machinability.

Common processes for preparing tungsten heavy alloys include mixing the desired amount of tungsten, iron, nickel or copper powder and then cold pressing and liquid phase sintering to near full density. During the liquid phase treatment, the matrix tungsten alloy melts and brings some tungsten into the solution, forming a microstructure through which large tungsten particles (20-60μm) are dispersed in the matrix alloy.

Application of Tungsten Fishing Weights

Tungsten Fishing Weights pendant 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 fishing pendant embodies the advantages different from other manufacturing materials.

1. High density: The density of tungsten alloys can reach 18.5g/cm3, which is much smaller in volume than other materials for the same mass.
2. Corrosion resistance: the chemical property of tungsten alloy is stable and does not react with any substance at normal temperature. Fishing pendants are easy to be oxidized if they are made of iron and used in contact with water for a long time.
3. High hardness: tungsten alloy is second only to diamond in hardness. It is hard to avoid collision with hard objects in the process of use. High hardness materials can make the fishing pendant difficult to fracture and deformation.
