Brass alloy C693, also known as leaded nickel silver, is a copper-nickel-zinc alloy with a composition of approximately 60% copper, 20% nickel, and 20% zinc, along with small amounts of lead. This specific formulation gives C693 excellent machinability, making it suitable for intricate machining operations and high-speed automatic lathes. The addition of nickel enhances the alloy's strength and corrosion resistance, making it valuable for marine and industrial applications. Brass C693 exhibits good electrical conductivity, making it a preferred choice for electrical connectors, switches, and terminals. Its lead content enhances its machinability further and improves its chip-breaking characteristics during machining. Brass alloy C693's golden hue and luster contribute to its appeal in decorative pieces, jewelry, and ornamental items. With its unique combination of machinability, strength, corrosion resistance, and aesthetics, brass C693 remains a versatile material, widely used in industries seeking functional and visually appealing solutions for various components and artistic works.
