For more details, pls directly contact us.

Our Monel 400 Wire is crafted from a nickel-copper alloy, blending roughly 67% nickel with 23% copper, plus a touch of iron and manganese for extra toughness. This mix gives it killer corrosion resistance against harsh elements like seawater, acids, and alkalis, while its non-magnetic properties make it a go-to for precision applications where magnetic interference could cause trouble. It’s strong, durable, and built to handle extreme conditions without missing a beat.

This wire thrives in demanding environments. It performs reliably at temperatures up to 1000°F (538°C), resists pitting and crevice corrosion, and maintains high tensile strength (70-110 ksi) for springs that need to endure stress and fatigue. We offer full customization—diameters, tensile strengths, coil designs, and finishes—so you get springs tailored to your exact needs, whether it’s for a tiny sensor or a critical aerospace component.
