Medical spring wire you can rely on 

For decades, Bekaert has been delivering high-quality spring wire to diverse industries, including construction, automotive, agriculture, energy, and medical devices. Our success is driven by collaboration and innovation. Through strong partnerships with spring manufacturers, design firms, and pharmaceutical companies, we have consistently driven innovation in the production of medical spring wire.

Our steel-based medical spring wire is designed for critical medical spring applications. It offers precise tolerances, higher spring rates, improved accuracy, enhanced fatigue resistance, and anti-corrosion properties vital for drug delivery systems. We can provide the medical spring wire you need based on your specifications, offering off-the-shelf solutions or customizing it to meet specific requirements.

Medical spring wire bend to your solution

We understand that your requirements can change and evolve over time, based on the nature of the applications where the spring wire is used and the changing standards and requirements that your product must fulfil to maintain its leading market position.

We pride ourselves on our ability to meet our customers’ needs. We approach our innovation and product development process from a strong foundation of four clear properties that define the characteristics of the medical spring wire we deliver to you:

  • What spring force is required by your medical device?
  • How long should it continue to perform?
  • Does it require increased corrosion resistance?
  • What are the design requirements you must meet?

Based on these varying parameters we can help you to find
the best solution.
