Chuck Metals stands out as a trusted manufacturer and supplier of Free Cutting Brass Rods right here in Singapore, Pulau Ujong. They cater to a variety of industries, including electrical, automotive, plumbing, and machining. What makes free cutting brass so special is its unique formulation that enhances machinability, making it perfect for precision-turned parts and high-speed machining tasks. Chuck Metals offers these rods in a range of sizes and grades, like IS 319 Type I/II and BS 2874 CZ121, all featuring smooth surface finishes and tight tolerances. With a strong focus on quality, timely delivery, and technical support, Chuck Metals delivers brass rod solutions designed for efficient manufacturing.
Typically, Free Cutting Brass Rods consist of about 57–63% copper and 1.8–3.5% lead, with the rest being zinc. The lead addition boosts machinability without compromising mechanical properties. These rods provide a tensile strength of 350–500 MPa and boast excellent corrosion resistance, particularly in neutral and mildly aggressive environments. Thanks to their outstanding chip formation and minimal tool wear, they allow for quicker production speeds and consistent finishes in CNC or lathe operations. Plus, the alloy shows good cold workability and moderate strength, making it ideal for precision applications.
