92.5WNiCu Tungsten High Specific Gravity Alloy Rings For Balance Weight With High Strength
Introduction of Tungsten Heavy Alloy:
Tungsten based high specific gravity alloys are also known as high-density tungsten based metals or high specific gravity tungsten alloys. They include tungsten nickel iron alloy (weak magnetic) and tungsten nickel copper alloy (non-magnetic). According to the American Standard ASTM b777-2007, tungsten nickel iron alloy and tungsten nickel copper alloy high-density tungsten base metals are divided into four grades, in which the tungsten content is 90%, 92.5%, 95% and 97% respectively, and the rest are nickel, iron, copper, etc.
Applications of Tungsten Nickel Copper Alloy:
Tungsten nickel copper alloy and tungsten nickel iron alloy products made by Zhengzhou Sanhui Tradings Co., Ltd are mainly applied in the following aspects:
Tungsten nickel copper alloy counter-balancing weight
Tungsten nickel copper alloy shielding material
Tungsten nickel iron alloy dart
Tungsten nickel iron alloy fishing pendant, tungsten alloy ball
Tungsten nickel iron alloy rivet ejector rod
Properties of tungsten heavy alloy:
W-Ni-Cu alloy is widely used because of its excellent properties such as high density, high strength, high hardness, good ductility, conductivity and thermal conductivity
