Our Monel 400 Spring Wire is crafted from a nickel-copper alloy, blending about 67% nickel with 23% copper, plus a touch of iron and manganese for extra toughness. This mix gives it unmatched corrosion resistance against harsh elements like seawater, acids, and alkalis, making it a go-to for springs in extreme environments. It’s strong, reliable, and built to last, no matter how tough the conditions.

This wire is a champ in harsh settings. It handles temperatures up to 1000°F (538°C), resists pitting and crevice corrosion, and stays non-magnetic, which is a big win for sensitive equipment like sensors or electronics. We offer full customization—think tailored diameters, tensile strengths, coil designs, and finishes—so you get springs that fit your project perfectly, whether it’s for a chemical reactor or an offshore platform.
