Monel K-500 Alloy Pipes – Age-Hardened Nickel-Copper Tubes for Harsh Environments
Product Overview
Monel K-500 pipes, also known by UNS N05500, are a precipitation-hardenable nickel-copper alloy that combines the excellent corrosion resistance of Monel 400 with enhanced strength and hardness. This is achieved through the addition of aluminum and titanium, followed by a thermal aging process. The resulting alloy exhibits approximately three times the yield strength and double the tensile strength of Monel 400, making it suitable for demanding applications in various industries. Monel K-500 maintains its mechanical properties across a wide temperature range, from cryogenic conditions up to 480°C (896°F), and is non-magnetic, which is advantageous in electronic and marine applications.
