A tungsten-nickel-iron alloy disc is a circular thin-sheet material primarily composed of tungsten, alloyed with nickel and iron, manufactured through powder metallurgy. With tungsten content typically at 85%-95%, the addition of nickel and iron improves tungsten’s brittleness, enhancing toughness and machinability. Its density, ranging from 16.5-18.5 g/cm³, is close to gold, making it ideal for high-density and high-strength applications. Due to its excellent mechanical properties and wear resistance, tungsten-nickel-iron alloy discs are commonly used in aerospace for counterweights, such as in aircraft and satellites, as well as in medical radiation shielding and industrial wear-resistant parts. The production process involves powder mixing, pressing, and sintering to ensure uniform structure and stable performance. These discs can be customized, with diameters from a few millimeters to hundreds of millimeters and thicknesses from 0.1 mm to several centimeters, meeting diverse industry needs. Their eco-friendly, non-toxic nature makes them a key material in modern high-tech manufacturing.
