Our Monel 400 Wire Springs are made from a high-performance nickel-copper alloy, with roughly 67% nickel and 23% copper, plus small amounts of iron and manganese for added strength. This alloy is a powerhouse when it comes to resisting corrosion, especially in seawater, acidic, and alkaline environments. It’s why our springs are a go-to for marine hardware, where durability and reliability are non-negotiable.

These springs are designed to handle the harsh realities of marine environments—think constant exposure to saltwater, high humidity, and fluctuating temperatures. They stay strong up to 1000°F (538°C), resist pitting and crevice corrosion, and are non-magnetic, which is a big plus for sensitive equipment like navigation systems or underwater sensors. Plus, we customize every aspect—diameter, coil size, tensile strength, and finish—to fit your specific marine hardware needs.
