Age-hardenable version of MONEL alloy 400 for increased strength and hardness. Good strength and ductility from -423 to 1200 °F. Pump shafts, doctor blades and scrapers, oil-well drill collars and instruments, electronic components, springs, valve trim, fasteners.

Age-hardenable Nickel-Copper alloy which combines the corrosion resistance of Alloy 400 with high strength corrosion fatigue and erosion resistance.

Alloy K-500 is a nickel-copper alloy, precipitation hardenable through additions of aluminum and titanium. This alloy retains the excellent corrosion resistant characteristics of 400 and has enhanced strength and hardness after precipitation hardening when compared with 400. Alloy K-500 has approximately three (3) times the yield strength and double the tensile strength when compared with 400. K-500 can be further strengthened by cold working before the precipitation hardening.

Typical application for the alloy which takes advantage of high strength and corrosion resistance are pump shafts, impellers, propeller shafts, valve components for ships and offshore drilling towers, bolting, oil well drill collars and instrumentation components for oil and gas production. It is particularly well suited for centrifugal pumps in the marine industry because of its high strength and low corrosion rates in high-velocity seawater. Should be annealed when welded and the weldment then stress relieved before aging.

High Performance Alloys, Inc. stocks Alloy K-500 in a range of sizes including 3/8" to 2-1/2" diameter cold drawn, annealed and aged, and 2-3/4" to 10" diameter hot finished and aged. Material can be supplied in random lengths, cut to order or machined to your specifications. Machining includes drilling, turning, tapping, threading, CNC shapes, flanges and more.
