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. I. High Strength and Tensile Performance The alloy’s tensile strength ranges from 700 to 1,000 MPa, primarily due to the rigid tungsten particle framework, with tungsten’s Mohs…
