Our Monel 400 Spring Wire is made from a nickel-copper alloy, packing about 67% nickel and 23% copper, with a dash of iron and manganese for extra toughness. This combo gives it killer corrosion resistance, especially against harsh stuff like acids, alkalis, and seawater. It’s the kind of material you want for springs that need to perform in brutal industrial settings without breaking a sweat.

This wire shines in environments where other materials would give up. It handles temperatures up to 1000°F (538°C), resists pitting and crevice corrosion, and stays non-magnetic, which is a huge plus for precision equipment. Whether you need springs for heavy machinery or sensitive systems, we customize everything—diameters, tensile strengths, coil designs, you name it—to fit your exact needs.
