The density of tungsten-nickel-iron alloy is one of its significant characteristics, usually ranging from 16.5 to 18.7g/cm³, and the specific value will vary with the content of tungsten. The higher the tungsten content, the greater the density of the alloy. This high density characteristic makes it irreplaceable in scenarios requiring counterweight, balance and radiation shielding. For example, in the aerospace field, it can be used as a counterweight block for spacecraft to ensure the flight attitude of the spacecraft through precise weight control; in the medical field, it can be used in radiation shielding devices, using high density to effectively block the penetration of rays.
In terms of mechanical properties, tungsten-nickel-iron alloy performs excellently. Its tensile strength is usually in the range of 700 – 1000MPa, which means it can withstand large tensile force without breaking easily. At the same time, it also has certain toughness, with an elongation of generally 2% – 10%, avoiding brittle fracture like pure tungsten, making it have better damage resistance when subjected to impact loads. In terms of hardness, the Rockwell hardness (HRC) of tungsten-nickel-iron alloy is mostly between 25 and 45, which has good wear resistance and is suitable for manufacturing parts that need to bear friction and wear, such as bearings and gears in precision instruments.
In addition, the alloy also has high compressive strength and can withstand large pressure while maintaining structural stability. The comprehensive performance of these mechanical properties makes tungsten-nickel-iron alloy not only have high strength to ensure structural stability, but also have certain toughness to cope with complex stress environments. Combined with its high density characteristics, it is widely used in many industrial fields. Different application scenarios have different requirements for the density and mechanical properties of the alloy. By adjusting the composition ratio and preparation process, these properties can be regulated in a targeted manner to meet specific use needs.
