Our Monel 400 Nickel Alloy Wire is crafted from a high-performance alloy blending about 67% nickel with 23% copper, plus a touch of iron and manganese for extra strength. This mix gives it killer corrosion resistance against harsh substances like acids, alkalis, and seawater, making it a go-to for springs that need to perform in extreme conditions. It’s tough, durable, and built to last, no matter what you throw at it.

This wire shines where others falter. It handles temperatures up to 1000°F (538°C), resists pitting and crevice corrosion, and stays non-magnetic, which is a big win for precision equipment like sensors or electronics. We offer full customization—diameters, tensile strengths, coil designs, and finishes—so you get springs that fit your project like a glove, whether it’s for a chemical plant, an offshore rig, or an aerospace system.
