Product Description

Tungsten alloy blocks can be made from tungsten based alloys with different compositions and ratios according to their different uses. W-Ni Cu alloy and W-Ni Fe alloy are the two most commonly used alloy materials, and there are also industries that require W-Ni Fe Mo products, which have high density and low usage.

Xi'an Kefeng Powder Metallurgy Co., Ltd. can produce products with the above three components, but most industries require tungsten nickel iron and tungsten nickel copper alloys.
The following is an introduction to tungsten nickel iron and tungsten nickel copper:

W-Ni Fe alloy
W-Ni Fe alloy is formed by mixed pressing and sintering of W, Ni, and Fe powders. Tungsten has the highest content, reaching 90% -97%, while nickel and iron act as binders. After liquid-phase sintering, a two-phase alloy is formed with a density similar to the theoretical density. Nickel is an essential element in liquid-phase sintering process, with a general content of 7%~1.5%. If the nickel content is too high, the heat and corrosion resistance of the alloy will be reduced. The iron content is generally between 3% and 1%, and if too much, the brittleness of the alloy will increase. Iron can improve strength and plasticity in this alloy, and this type of alloy has a certain degree of magnetism. Due to its low iron content, the product is weakly magnetic and can be used as a core material for armor piercing shells, high momentum killing fragments such as submunitions, counterweights, and other industrial fields. Compared with W-Ni Cu alloy, this alloy has better strength and plasticity.

W-Ni Cu alloy
W-Ni Cu alloy is mainly formed by mixed pressing and sintering of W, Ni, and Cu powders. Among them, the W content is generally 90%~97%. After adding Ni and Cu binders, a two-phase alloy is formed after liquid-phase sintering, with a density close to the theoretical density. The remaining content in this alloy, except for W and Ni, is the copper content. Copper can improve the strength and plasticity of tungsten alloys in alloys. In terms of performance, this alloy has no magnetic properties for special applications, and other physical properties are the same as the overall performance of tungsten alloy.
