CuZn40

CuZn40 is a brass alloy, a metal composed primarily of copper and zinc. The designation CuZn40 specifically indicates that the alloy contains approximately 40% zinc by weight, with the remaining 60% being copper. This composition places it within the category of alpha-beta brasses or sometimes referred to as Muntz metal if the zinc content is closer to 40%.

Alloys like CuZn40 exhibit a favorable combination of properties. They are known for their good strength, ductility, and excellent corrosion resistance, particularly in marine environments. The presence of zinc significantly affects the alloy's mechanical properties compared to pure copper, offering increased hardness and tensile strength while maintaining workability.

CuZn40 is often used in applications where a balance of strength, formability, and resistance to dezincification is required. Common uses include plumbing fittings, marine hardware, architectural components, and fasteners. Its machinability is generally good, allowing for intricate shaping and production of precision parts. The color of CuZn40 is typically a yellowish hue, characteristic of brass. It can be readily joined by soldering, brazing, and welding.
