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.

The density of tungsten-nickel-iron alloy, typically ranging from 17.0 to 18.5 g/cm³, is a critical factor influencing its application scenarios. This high-density characteristic profoundly impacts the alloy’s use across functional realization, structural design, and scenario adaptability.

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.

Tungsten-nickel-iron alloy is a high-density alloy with tungsten as the base (typically 80%–98% tungsten content), incorporating nickel, iron, and other elements. It boasts a range of unique physical, chemical, and mechanical properties, finding wide use in aerospace, defense, medical devices, and industrial manufacturing.
