Monel K-500

MONEL® alloy K-500 is a nickel-copper alloy which combines the excellent corrosion resistance of MONEL alloy 400 with the added advantages of greater strength and hardness. The increased properties are obtained by adding aluminum and titanium to the nickel-copper base, and by heating under controlled conditions so that submicroscopic particles of Ni3 (Ti, Al) are precipitated throughout the matrix. The thermal processing used to effect precipitation is commonly called age hardening or aging.

Super alloys contain many elements in different combinations so as to achieve a desired result. They have the ability to function at very high temperatures and under severe mechanical stress, and also where high surface stability is required. They have good creep and oxidation resistance. There are three groups of alloys, namely cobalt-based, nickel-based, and iron-based alloys.
