90WNiFe Slotted Tungsten Fishing Beads For Fly Tying Fishing Weight
Slotted Tungsten Alloy Fishing Beads For Fly Tying Fishing Weight
Tungsten alloy fishing beads are a kind of tungsten base 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 can reach 15.20 ~ 18.70g/cm3, and weigh tungsten alloy or high density alloy material. Because tungsten alloys weigh more than twice as much as steel.

Tungsten Alloy Fishing Beads Picture:
What is Tungsten Alloy 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, high thermal conductivity: 5 times that of die steel; Low thermal expansion coefficient: only 1/2-1/3 of steel, good electrical conductivity; Good weldability and machinability.
A common process for preparing heavy tungsten alloys involves 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 base tungsten alloy melts and brings part of tungsten into the solution, forming large tungsten particles (20-60 μm) dispersed in the base alloy.
Application of Tungsten Alloy Fishing Beads
Tungsten alloy fishing gear pendant is a kind of tungsten alloy 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 alloy hook embodies the advantages different from other manufacturing materials.
- High density: the density of tungsten alloy can reach 18.5g/cm3, which is much smaller than other materials at the same mass.
- Corrosion resistance: tungsten alloy has stable chemical properties and does not react with any substance at room temperature. If the fishing pendant is made of iron, it is easily oxidized after long contact with water.
- High hardness: Tungsten alloy is second only to diamond in hardness. It is difficult to avoid collision with hard objects during use. High hardness materials can make the fishing pendant resistant to fracture and deformation.
