The application of tungsten-nickel-iron alloy in precision instruments highlights the comprehensive advantages of its high density, high stability and excellent mechanical properties, providing important support for the high-precision operation of instruments. Precision instruments have strict requirements on the weight control, stability and anti-interference ability of components, and tungsten-nickel-iron alloy has become an ideal material for many core components by virtue of its unique properties.
In various precision measuring instruments, such as laser interferometers and coordinate measuring machines, this alloy is often used as a counterweight component. By precisely adjusting the center of gravity of the instrument, it reduces the impact of external vibration on measurement accuracy and ensures the accuracy of measurement data. In the field of optical instruments, such as the lens barrels and focusing mechanisms of high-end microscopes and astronomical telescopes, tungsten-nickel-iron alloy components can effectively inhibit dimensional deformation caused by temperature changes, ensure the stability of the optical system, and improve imaging quality.
For precision rotating equipment, such as rotors of high-speed centrifuges and balance weights of precision motors, the high density of the alloy can achieve dynamic balance in a small volume, reduce vibration and noise during equipment operation, and prolong service life. At the same time, its good wear resistance and corrosion resistance enable it to maintain long-term stable performance in the complex working environment of precision instruments, reducing maintenance costs. In addition, in some precision electronic instruments that need to shield electromagnetic interference, the magnetic and high-density characteristics of tungsten-nickel-iron alloy can form an effective electromagnetic shielding layer, protecting the sensitive components inside the instrument from external electromagnetic signals and ensuring the normal operation of the instrument.
