Based in the heart of Hamilton, New Zealand, Hemi Metals is dedicated to supplying industry with high-performance materials that also respect our environment. Our Lead Free Brass Rod is a prime example of this commitment, offering a responsible solution for modern manufacturing. We understand the critical need for safer, compliant materials without compromising on quality or performance, providing a reliable local source for engineers and fabricators who demand excellence and are looking toward a more sustainable future.
This material is precision-engineered to meet stringent international standards, primarily composed of a carefully balanced mix of copper and zinc, often with additions like silicon or bismuth to enhance its properties. The result is a rod that delivers excellent machinability, strong corrosion resistance, and impressive tensile strength. It’s designed to perform reliably under pressure, making it a durable and trustworthy choice for a wide range of demanding applications where traditional leaded brass was once the only option.

Yes, lead-free brass rods can be used for electrical applications due to their excellent conductivity, corrosion resistance, and durability, making them suitable for connectors, terminals, and other electrical components.
Lead-free brass rods are manufactured by melting a blend of copper, zinc, and other metals, then extruding the mixture into rods. The process involves cooling, shaping, and precision cutting for consistency.
Store lead-free brass rods in a dry, cool environment, away from moisture and corrosive elements. Keep them on pallets or racks, ensuring proper ventilation and protection from physical damage and oxidation.
You’ll find our Lead Free Brass Rod is incredibly versatile, perfectly suited for anything from intricate plumbing fittings and potable water system components to marine hardware and architectural detailing. Its superior machinability means it can be easily turned, milled, and threaded into complex parts. This makes it an essential material for manufacturers creating products for the food and beverage industry, medical gas systems, and any application where safety and material purity are non-negotiable, proving that responsible manufacturing doesn’t mean sacrificing capability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
