Brass rod with a Cu63/Zn37 composition—commonly known as Cartridge Brass or C27200 alloy—is a versatile copper-zinc alloy characterized by its excellent cold workability, moderate strength, corrosion resistance, and attractive golden appearance. With 63% copper and 37% zinc, this brass grade strikes a balance between formability and mechanical performance, making it a preferred choice for machined components, decorative parts, and functional hardware.
