In the vast landscape of modern industry, tungsten-nickel-iron alloy stands out as a multifaceted material due to its unique properties, playing a pivotal role across numerous fields. From high-precision equipment in aerospace to robust tools in oil drilling, from protective components in medical devices to precision parts in the automotive industry, this alloy is ubiquitous.

The physical properties of tungsten-nickel-iron alloy include high strength, good ductility, high hardness, wear resistance, and a low thermal expansion coefficient, while its chemical properties encompass excellent corrosion resistance, high-temperature oxidation resistance, chemical stability, and erosion resistance. These chemical properties arise from the synergistic effects of the constituent elements and the alloy’s microstructural characteristics.

Tungsten-nickel-iron alloy, composed of tungsten, nickel, iron, and other elements, features high strength, high hardness, excellent corrosion resistance, and radiation shielding capabilities. It is widely used in aerospace, aviation, military, and electronics fields, such as for manufacturing counterweights, shielding components, and high-temperature structural parts. Common production methods include powder metallurgy, metal injection molding, and chemical co-precipitation.

Tungsten-nickel-iron alloy is a material with tungsten as the matrix (typically 90%–98% tungsten content), formed by adding nickel, iron, and other elements. Its physical properties stem from the synergistic effect of tungsten’s high hardness and the toughness of the nickel-iron binder phase, which can be optimized by adjusting composition ratios and preparation processes.
