MONEL K-500（UNS N05500） WIRE
Age-Hardenable Nickel-Copper Alloy for High Strength and Corrosion Resistance
MONEL K-500 bar is widely used for machined components requiring exceptional corrosion resistance in aggressive process media. The alloy resists pitting, crevice corrosion, and chloride stress corrosion cracking, and maintains excellent corrosion performance in welded and fabricated structures due to its extremely low carbon and silicon.
As a professional Chinese nickel-based alloy manufacturer, we supply MONEL K-500 bars with stable chemistry, consistent mechanical properties, and flexible dimensional customization for global industrial users.
Typical supply range (custom sizes and tolerances available upon request):
