Monel Nickel-Copper alloy K-500 combines the excellent corrosion resistance characteristic of Monel alloy 400 with the added advantages of greater strength and hardness. Increased properties are obtained by adding Aluminum and Titanium to the Nickel-Copper base, and by heating under controlled conditions. The thermal processing used to effect precipitation is commonly called age hardening or aging.
The corrosion resistance of Monel alloy K-500 is similar to alloy 400 except in the age-hardened condition, alloy K-500 has a greater tenancy toward stress-corrosion cracking in some environments. |
