For more details, pls directly contact us.

Our Monel 400 Wire is crafted from a nickel-copper alloy, blending about 67% nickel with 23% copper, plus a dash of iron and manganese for extra toughness. This mix gives it killer corrosion resistance against harsh elements like seawater, acids, and alkalis, while maintaining its strength at high temperatures up to 1000°F (538°C). It’s the kind of material you want for springs that need to perform in extreme heat without breaking a sweat.

This wire is a champ in tough conditions. It resists pitting and crevice corrosion, stays non-magnetic for sensitive applications, and holds up under stress and fatigue. We offer full customization—diameters, tensile strengths, coil designs, and finishes—so you get springs that fit your high-temperature project like a glove, whether it’s for an oil refinery or a jet engine.
