Our Monel 400 Spring Wire is crafted from a nickel-copper alloy, blending roughly 67% nickel with 23% copper, plus small amounts of iron and manganese for extra toughness. This mix gives it unbeatable resistance to seawater, acids, and alkalis, making it a superstar for marine environments. It’s strong, reliable, and built to last, even when exposed to the harshest conditions.

This wire thrives where others fail. It handles temperatures up to 1000°F (538°C), resists pitting and crevice corrosion, and stays non-magnetic, which is critical for sensitive marine equipment like navigation systems. We offer full customization—diameters, tensile strengths, coil designs, and finishes—so you get exactly what your marine project needs.
