Elgiloy Springs

Elgiloy springs are made from a unique cobalt-based alloy that incorporates copper, nickel, chromium, and molybdenum. This distinctive formulation ensures that the springs maintain their mechanical properties even under severe conditions, making them a preferred choice for a wide array of spring applications.

Material Properties

Elgiloy springs offers several benefits essential for rigorous applications:

  • Efficient Strength-to-Weight Ratio: The alloy delivers notable strength while keeping the overall weight low—a crucial factor in applications where minimising mass is important.
  • Robust Corrosion Resistance: Capable of withstanding exposure to corrosive environments, including saltwater and acidic conditions, Elgiloy springs are built to last.
  • High Fatigue Endurance: Engineered to tolerate repeated cycles of stress, these springs maintain their integrity over extended use.
  • Temperature Stability: Elgiloy retains its performance at elevated temperatures, making it suitable for applications experiencing significant heat fluctuations.
  • Versatile Fabrication: The alloy’s ease of forming allows for the production of intricate, custom designs without compromising performance.

    Each element in the alloy plays a vital role: cobalt provides overall strength and resistance to corrosion; nickel enhances ductility; copper improves workability; and chromium, together with molybdenum, further boosts corrosion resistance and overall durability.

Applications Across Industries

Thanks to their resilience and reliable performance, Elgiloy springs are used in a variety of challenging sectors:

  • Aerospace Engineering:  In aircraft engines and structural components, the ability to withstand extreme conditions is essential for safe, continuous operation.
  • Medical Devices:  The biocompatibility and endurance of Elgiloy springs make them suitable for precision surgical instruments and implantable devices.
  • Oil and gas industry: used in downhole tools and blowout preventers (BOPs) preventing failures that could lead to costly incidents during drilling operations.
