Nimonic Springs

Nimonic springs are nickel-based superalloy springs that are engineered to deliver reliable performance in high-temperature, high-stress and corrosive environments. By fine-tuning alloy composition, heat treatment and coil geometry, the mechanical and thermal characteristics can be optimised to meet precise application demands.

Properties

Thanks to their carefully controlled nickel-chromium-cobalt matrix, Nimonic springs exhibit exceptional strength at elevated temperatures, outstanding resistance to thermal fatigue and robust performance in oxidising or corrosive atmospheres—ensuring consistent load behaviour even under the most arduous conditions.

Benefits

As long-standing Nimonic spring manufacturers, we can confirm that our customers favour these springs for the following reasons:

  • Thermal Stability: Retain load characteristics across rapid temperature swings up to 700 °C.
  • Extended Service Life: Exceptional resistance to cyclical loading and thermal fatigue reduces replacement intervals.
  • Low Maintenance: Minimsed oxidation and corrosion minimise downtime and upkeep costs.
  • Lightweight Strength: High strength-to-weight ratio is ideal for weight-sensitive assemblies.
  • Tailorable Performance: Alloy tweaks and heat-treatment schedules allow precise control over spring rate and temperature capability.
