Home Products High Performance Alloys Brush 1915 and Brush 1916 Alloys CORROSION RESISTANT BRUSH 1915® & BRUSH® 1916 ALLOYS Materion’s Brush 1915 and Brush 1916 alloys (UNS C19150) are leaded nickel copper alloys that provide high strength and good formability. These alloys exhibit excellent corrosion resistance, including marine corrosion and biofouling. Adding lead to these alloys improves machinability, acts as a lubricant and in the free machining grades, allows for chip break up. These free machining alloys offer high levels of machinability without harming performance and keeping overall costs low for volume specific processes such as cold heading or cold forming. ADVANTAGES OF FREE MACHINING LEADED NICKEL COPPER ALLOYS Our leaded nickel copper, free machining alloys, Brush 1915 & Brush 1916, were developed with a unique precipitation hardening process, creating a material with high strength, high corrosion resistance, high tensile and yield strength with good resistance to stress. Brush 1915 & Brush 1916 alloys provide many advantages, including: Excellent machinability (70 percent of free-cutting brass) Excellent cold headability Excellent surface finish Good conductivity Close diameter control Microstructural consistency The high corrosion resistance, high tensile and yield strength, and good resistance to stress make Brush 1915 and Brush 1916 alloys a successful alternative for copper beryllium alloys.
