High-Temperature Resistance WNiCu Tungsten Heavy Alloy Pins Tungsten Heavy Alloy Pins are made of tungsten base (tungsten
content is generally 80%-98%) and a small amount of nickel, iron,
copper, cobalt, molybdenum, chromium and other elements. The
density of high specific gravity tungsten alloy can reach
15.20~18.70g/cm3, also known as high specific gravity tungsten
alloy or high density alloy material. Because tungsten alloy weighs
more than twice as much as steel. Introduction and Feature of Tungsten Heavy Alloy PinsTungsten alloy has a series of excellent properties, high specific
gravity: general specific gravity 16.5-18.75g/cm3, high strength:
tensile strength 700-1000mpa, strong light absorption: higher than
the general lead specific gravity 30-40%, high thermal
conductivity: die is 5 times of steel; Low thermal expansion
coefficient: the capacity is only 1/2/3 of steel, with good
electrical conductivity, welding resistance and cutting resistance. The common method of preparing heavy tungsten alloys is to mix the
desired tungsten, iron, nickel or copper powder and then cold press
the liquid phase to near full density. During the liquid phase
treatment, the matrix tungsten alloy melts, and part of the
tungsten enters the solution, forming the microstructure of large
tungsten particles (20-60 m) dispersed in the matrix alloy.
Heavy Tungsten Alloy Pendant Picture:
Application of Tungsten Heavy Alloy Pins- Tungsten Heavy Alloy Pins are made of high gravity tungsten
alloys. Further improve the wear resistance, hardness, strength and
heat resistance of the alloy, to better ensure the consistency of
products. Because of these characteristics, tungsten-iridium pores
have become an integral part of the high-tech crystal glass
industry.
