Rivet Brass Rods are typically made up of 60% copper and 40% zinc (often referred to as CZ121 or CuZn40), striking a perfect balance between strength, ductility, and corrosion resistance. This alloy boasts excellent cold working properties and remarkable machinability. The rods have a tensile strength ranging from about 350 to 500 MPa and good elongation values (up to 25%), with a Brinell hardness of roughly 100 to 120 HB. Their consistent grain structure and smooth surface finish make them perfect for heading, forming, and machining applications, especially where reliable performance and ease of fabrication are crucial.

Rivet Brass Rods find extensive use in creating cold-headed and hot-forged rivets, fasteners, electrical connectors, switchgear components, pins, and terminals. Their high machinability and excellent formability make them perfect for crafting small precision parts in the automotive, electrical, and general hardware sectors. These rods are also utilized in making plumbing fittings, architectural hardware, and decorative features. Thanks to their corrosion resistance and strength, they’re well-suited for outdoor and marine applications as well. The alloy’s workability allows for easy shaping and manipulation, making it a go-to choice for various manufacturing needs.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
