Chuck Metals offers these rods in different diameters and lengths, ensuring superior dimensional accuracy and finish. With a commitment to international standards, quick turnaround times, and expert support, they deliver reliable brass material solutions tailored to meet customer needs.
Typically, Brass Rod Grade 1 is made up of about 60% copper and 40% zinc, providing excellent machinability and moderate tensile strength that ranges from 350 to 500 MPa. This grade is designed for easy cutting, often with a small addition of lead (around 2-3%) to enhance chip-breaking during machining. It boasts good corrosion resistance, particularly in water-based and mildly corrosive environments. Plus, it’s non-magnetic, can be easily cold-worked, and offers a smooth surface finish. This makes it a great choice for soldering, brazing, and forming operations in high-precision applications.

You’ll find Brass Rod Grade 1 commonly used in the production of precision components like valve stems, electrical terminals, connectors, nuts, bolts, lock bodies, taps, and sanitary fittings. Its excellent machinability makes it a favorite for high-speed automatic screw machines and CNC equipment. In the electrical and plumbing sectors, it’s preferred for its conductivity, corrosion resistance, and ease of fabrication. Thanks to its workability and durability, this brass grade is also utilized in automotive components, decorative hardware, and small mechanical assemblies that demand fine detail and tight tolerances.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
