With a keen focus on precision-engineered non-ferrous metals, Neil Metals offers top-notch brass rods crafted for exceptional machinability and a smooth surface finish. These Free Cutting Brass Rods find their place in various industries that require quick production rates and precise dimensional tolerances, including automotive, electrical, plumbing, and hardware sectors. Committed to quality, customization, and timely delivery, Neil Metals guarantees that its brass products meet international standards. The company is a trusted partner for durable, consistent, and cost-effective solutions in high-speed machining and component manufacturing.
Free Cutting Brass Rods generally comprise about 57–61% Copper, 35–40% Zinc, and 0.8–3.5% Lead, depending on the specific grade, like IS 319 or CZ121. The inclusion of lead boosts machinability by enhancing chip-breaking properties and minimizing tool wear. These rods showcase a tensile strength ranging from 350–500 MPa, along with good elongation and hardness that are perfect for machining tasks. They also provide excellent corrosion resistance, electrical conductivity, and a shiny finish. Free Cutting Brass is particularly well-suited for high-speed automatic lathes and CNC machines, ensuring precise cuts, minimal tool damage, and impressive production efficiency.
