High Performance Machined Heavy Tungsten Alloy RingsHeavy tungsten alloy rings 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 gravity tungsten alloy is as high as 15.20~18.70g/cm3,
also known as gravity tungsten alloy or high-density alloy
material. Because tungsten alloy weighs more than twice as much as
steel.

Heavy Tungsten Alloy Rings Picture:
Introduction and Feature of Heavy Tungsten Alloy RingsTungsten alloy has a series of excellent properties, high specific
gravity: general gravity lead 16.5-18.75g/cm3, high strength:
tensile strength 700-1000mpa, strong light absorption capacity:
30-40% higher than general gravity lead, thermal conductivity: 5
times that of modulus steel; low thermal expansion coefficient:
only 1/2-1/3 of carbon steel, good electrical conductivity, good
welding and processing skills. A common process for making heavy tungsten alloys involves mixing
the desired amount of tungsten, iron, nickel or copper powder,
followed by cold pressing and liquid phase sintering to near full
density. During the liquid phase treatment, the matrix tungsten
alloy melts and some tungsten enters the solution to form a
microstructure, so that larger tungsten particles (20-60m) are
dispersed in the matrix alloy.
