Home Products Alloys Leaded Nickel Copper Alloys LEADED NICKEL-COPPER ALLOYS Nickel copper alloys provide improved strength and corrosion resistance while retaining good formability. They have excellent resistance to corrosion, including marine corrosion and biofouling. Adding lead improves machinability, acts as a lubricant, and in the free machining grades, improves chip break up. Our free machining alloys are designed to improve machinability without harming performance, keeping overall costs low for volume specific processes such as cold heading/cold forming. FREE MACHINING ALLOYS Our leaded nickel copper free machining alloys are available in two compositions: Brush 1915 Brush 1916 LEARN MORE WITH OUR GUIDE TO HIGH PERORMANCE ALLOYS To learn more about nickel copper alloys, download our comprehensive, 84-page Guide to High Performance Alloys. The guide important details about the physical and mechanical properties of our standard alloys, application and engineering data as well as processing and fabrication recommendations.
