Brass 260 (UNS C26000) is a yellow cartridge brass alloy composed of 70% copper and 30% zinc, with added lead for improved machinability. It is a ductile and corrosion-resistant alloy commonly used for ammunition casings, fasteners, electrical components, and architectural applications due to its strength and ability to be cold worked. The rectangular bar shape allows for various fabrication processes like machining, cold forming, and manufacturing components that require good finishing capabilities.
