Our Monel 400 Spring Wire is crafted from a nickel-copper alloy, packing about 67% nickel and 23% copper, with a touch of iron and manganese for extra toughness. This blend gives it top-notch corrosion resistance, especially against harsh substances like sour gas, seawater, and acids. It’s the kind of material you want for springs that need to perform in the brutal conditions of oil and gas exploration and production.

This wire is a beast in extreme environments. It holds up at temperatures up to 1000°F (538°C), resists pitting and crevice corrosion, and stays non-magnetic, which is crucial for sensitive equipment like sensors. We offer full customization—think tailored diameters, tensile strengths, coil designs, and finishes—so you get exactly what your oil and gas project needs.
