Our Monel 400 Spring Wire is crafted from a high-performance nickel-copper alloy, blending about 67% nickel with 23% copper, plus traces of iron and manganese. This unique mix gives it unmatched resistance to corrosion, especially in harsh chemical settings like acidic and alkaline environments. It’s tough, durable, and built to last, making it the go-to choice for springs that need to perform under pressure—literally and figuratively.

What sets our wire apart is its ability to withstand corrosive substances like sulfuric acid, hydrofluoric acid, and seawater, all while maintaining its strength and flexibility. Whether it’s high temperatures up to 1000°F or constant exposure to aggressive chemicals, our Monel 400 wire keeps its cool. Plus, it’s non-magnetic, which is a big win for applications where magnetic interference could cause issues, like in precision instruments or sensitive equipment.
