The applications of tungsten-nickel-iron alloy as a shielding material in the medical field stems from its unique physical properties, such as high density, good chemical stability, and excellent radiation shielding capabilities. With a density typically ranging from 16.5 to 18.75 g/cm³, its ability to attenuate X-rays, γ-rays, and other radiation is comparable to traditional lead shielding materials. Moreover, it is less prone to fracturing or deforming due to impacts or vibrations, giving it a clear advantage in medical radiation protection scenarios.

As an important product of the inorganic metal tungsten, tungsten alloy has an extremely wide range of applications, including electronics, automotive, defense, military, aerospace, aviation, maritime, optoelectronics, and medical fields.

Carbon plays a critical role in regulating the microstructure and mechanical properties of tungsten-nickel-iron alloys, with its influence on alloy hardness primarily achieved through altering the microstructure, forming carbides, and modulating interface bonding states.

Tungsten-nickel-iron alloy, a crucial tungsten-based alloy, uses tungsten as its matrix, with tungsten content typically ranging from 90% to 98%, forming the alloy’s foundational structure. Nickel and iron, as primary additive elements, play critical roles, with common nickel-to-iron ratios of 7:3 or 1:1.
