Based in the industrious city of Hamilton, New Zealand, Hemi Metals proudly manufactures and supplies a comprehensive range of high-quality materials, with our Naval Brass Rod standing as a testament to our commitment to excellence. We understand that our clients need reliability and performance, which is why this specific alloy is produced to meet the most demanding marine and industrial specifications. It’s a product crafted not just for its superior qualities, but to be a dependable component in the projects that help build and maintain our nation’s infrastructure and maritime endeavors.
This particular brass rod is defined by its unique composition, primarily a blend of approximately 60% copper and 39% zinc, with about 1% tin added for a crucial advantage. The inclusion of tin is the key, significantly enhancing its resistance to corrosion, especially from saltwater, while also improving its overall strength and durability. This results in a material that offers excellent machinability, allowing for easy fabrication, alongside good fatigue resistance. It’s this synergy of properties that makes it such a trusted choice for challenging environments where failure is not an option.

Naval brass rods are manufactured by melting a blend of copper, zinc, and tin, followed by casting, hot rolling, and cold drawing into desired rod shapes, ensuring strength, corrosion resistance, and durability.
Yes, naval brass rods are available in various finishes, including polished, matte, or brushed. These finishes enhance aesthetics, corrosion resistance, and are suitable for different marine, industrial, and engineering applications.
Store naval brass rods in a dry, cool environment, away from moisture and chemicals. Use protective covers to prevent scratches, and avoid direct contact with corrosive materials to maintain their quality.
The uses for this robust material are extensive, famously earning its name from critical marine applications such as shipbuilding components, propeller shafts, and underwater fittings. Beyond the sea, its excellent combination of strength and corrosion resistance makes it ideal for heavy-duty industrial use, including constructing valves, pumps, and fasteners in chemical plants. It’s also a preferred material for crafting hardware like bolts, nuts, and architectural accents, proving its versatility in both demanding engineering contexts and projects where longevity and a classic appearance are equally important.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
