Our Monel K500 Spring Wire is crafted from a nickel-copper alloy, blending roughly 66% nickel with 30% copper, plus aluminum and titanium to boost its strength and corrosion resistance. This alloy is a powerhouse, offering higher strength than Monel 400 while maintaining exceptional resistance to seawater, acids, and alkalis. Its non-magnetic properties make it a go-to for precision springs in applications where magnetic interference could spell trouble.

This wire thrives in demanding environments. It handles temperatures up to 1000°F (538°C), resists pitting and stress-corrosion cracking, and delivers tensile strengths of 100-160 ksi for springs that endure high 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.
