Tungsten-nickel copper alloy rod W152 is magneto-free tungsten-nickel copper
Tungsten has a density of 19.25 g/cm 3, about 2.5 times that of iron (7.87 g/cm 3), and is one of the heaviest metal elements in the periodic series. High density tungsten alloys (i.e. high specific gravity tungsten alloys) based on this characteristic have become an important application field of tungsten. High density tungsten alloy can be made by adding nickel, iron, copper and a few other elements into tungsten powder by liquid phase sintering process. According to different components, high-density tungsten alloys can be divided into two alloy systems: tungsten-nickel-iron and tungsten-nickel-copper. The WNiFe series is weakly magnetic, while the WNiCu series is non-magnetic. Through liquid phase sintering, its density can reach 17 ~ 18.6 g/cm, high density tungsten alloy made by liquid phase sintering in addition to high density has better impact performance than pure tungsten, its main use is to manufacture high penetration of armor piercing bullets. Tungston-based high specific gravity alloy rod is more widely used in the processing of clocks and watches, golf clubs, sports cars, aerospace and other fields used in the balance weight block. Tungsten based high specific gravity alloy plate is widely used in radiation shielding fields, such as medical treatment, nuclear industry, etc.
