Alloy K-500 (UNS N05500) is a nickel-copper alloy with agehardening properties imparted by alloying additions of aluminium and titanium. Its basic composition is similar to that of Alloy 400 but the alloying additions make it age hardenable under controlled conditions of temperature and time.
The alloy can be delivered in the annealed, stress equalised, hot finished or age-hardened conditions. This alloy is characterised by:
• excellent corrosion resistance in an extensive range of natural and chemical environments
• excellent resistance to chloride-ion stress-corrosion cracking
