Chuck Metals is a well-respected manufacturer and supplier of Lead Free Brass Rods based in Singapore, Pulau Ujong. They focus on providing eco-friendly and RoHS-compliant solutions for various industries, including plumbing, electrical, and medical. These lead-free brass rods are designed to be a safer alternative to traditional leaded brass, offering impressive machinability, corrosion resistance, and strength—all without the harmful effects of lead. Chuck Metals offers these rods in a range of sizes and compositions, such as CW510L, CW511L, and ECO BRASS®, ensuring they meet international standards. With a commitment to consistent quality and timely delivery, Chuck Metals is dedicated to supporting sustainable and health-conscious manufacturing needs.
Typically, Lead Free Brass Rods consist of 58–63% copper, blended with zinc and small amounts of silicon, bismuth, or other elements to improve machinability and strength. These alloys can achieve tensile strengths between 400–600 MPa while still providing good corrosion resistance and dimensional stability. Unlike traditional free-cutting brass, lead-free versions eliminate toxic lead content but still allow for efficient chip breaking and smooth surface finishes. They comply with drinking water standards like NSF/ANSI 61, making them safe for use in potable water systems.
