High Density WNiFe Heavy Tungsten Alloy Sinkers For Fishing
ApplicationHeavy tungsten alloy sinkers have a series of excellent
characteristics, its remarkable characteristics are: general
proportion 16.5-18.75g/cm3, high strength: tensile strength
700-1000mpa, strong light absorption capacity: 30-40% higher than
lead, high thermal conductivity. Large welding coefficient: 5 times
of section steel, low thermal expansion coefficient: only 1/2-1/3
of steel, good electrical conductivity, good welding and processing
ability. Heavy tungsten alloy sinkers SPECIFICATION | Chemical Composition | 90%W | 93%W | 95%W | 97%W | | State | Sinter | Vacuum | Forge | Sinter | Vacuum | Forge | Sinter | Vacuum | Sinter | Vacuum | Density

Heavy tungsten alloy sinkers Picture:
What is Heavy Tungsten Alloy Sinkers?Heavy tungsten alloy precipitation plate has high density, high
strength, high hardness (commonly known as 3H alloy), ductility,
electrical conductivity, thermal conductivity and other good
comprehensive excellent performance. It plays an important role in
weapon manufacture and national defense construction. Tungsten
alloy materials have been widely used in industry, aerospace and
civil industry (such as electrical industry, drilling industry,
etc.), and has become a popular dual-use alloy materials. Tungsten alloys are also known as tungsten alloys because they
carry more than twice the weight of steel. High specific gravity
tungsten alloys are usually refractory metals composed of WNFe-Fe,
WNNi-Cu or even WNNi-Cu-Fe. Some tungsten alloys are added to 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 Sinkers- Heavy tungsten sink is a kind of tungsten alloy material made from
fishing gear. Tungsten alloy fishing tackle has the advantages of
high density, small size and various shapes. Applicable to all
ranges. Tungsten goldfish pendant can be divided into worm pendant,
bucket pendant, needle pendant, bullet pendant, water drop pendant.
