Our Monel K500 Spring Wire is crafted from a nickel-copper alloy, blending about 66% nickel with 30% copper, plus aluminum and titanium to boost its strength and corrosion resistance. This alloy is a beast, offering higher strength than Monel 400 while maintaining exceptional resistance to aggressive corrosives like acids, alkalis, seawater, and sour gas. It’s the go-to material for springs that need to thrive in the most punishing environments.

This wire is a powerhouse in extreme conditions. It handles temperatures up to 1000°F (538°C), resists stress-corrosion cracking and pitting, and stays non-magnetic, which is critical for sensitive equipment like sensors. We offer full customization—diameters, tensile strengths, coil designs, and finishes—so you get springs that fit your project perfectly, whether it’s for a chemical reactor or a subsea system.
