High Density 90WNiFe Tungsten Fly Tying For Fishing
Tungsten Fly Tying For Fishing are kind of a tungsten-based alloy (tungsten content is generally 80%~98%). A small amount 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 as high as 15.20~18.70g/cm3, also known as high specific gravity tungsten alloy or high density alloy material. Because tungsten alloys weigh more than twice as much as iron or steel.

Tungsten Fly Tying For Fishing Picture:
Introduction of Tungsten Fly Tying For Fishing
Tungsten heavy alloy has a series of excellent properties, significant ratio: general ratio is 16.5-18.75g/cm3, high strength: tensile strength 700-1000mpa, strong ray absorption capacity: its capacity is 30-40% higher than lead, thermal conductivity Large: 5 times that of die steel; small thermal expansion coefficient: only 1/2-1/3 of steel, good electrical conductivity; good weldability and machinability.
A common process for preparing tungsten heavy alloys involves mixing the desired amount of tungsten, iron, nickel or copper powder, followed by cold pressing and liquid phase sintering to nearly full density. During the liquid phase treatment, the base tungsten alloy melts and brings some tungsten into the solution, forming a microstructure through which large tungsten particles (20-60 μm) are dispersed in the base alloy.
Application of Tungsten Fly Tying For Fishing
Tungsten Alloy Beads are a fishing appliance made of tungsten alloy material. Tungsten alloy fishing pendant has large density, small volume and different shapes, which is suitable for the selection of various river sections. Tungsten alloy fishing pendant shows different advantages from other manufacturing materials.
- High density: the density of tungsten alloy can reach 18.5g/cm3, which is much smaller than other materials in volume under the same mass.
- Corrosion resistance: the chemical properties of tungsten alloy are stable and do not react with any substance at room temperature. Yuzhuzi is used in contact with water for a long time. If it is an iron material, it is easy to be oxidized.
- High hardness: the hardness of tungsten alloy is second only to diamond and has considerable hardness. It is inevitable that the fishing pendant will collide with hard objects during use. High hardness materials can make the fishing pendant not easy to fracture and deformation.
