For over [number] years, Hemi Metals has been a trusted name in Hamilton, New Zealand, producing high-quality materials for demanding industries. We take pride in our precision manufacturing of High Tensile Brass Rods, a robust alloy engineered for superior strength. Supplied directly from our facility, these rods consistently deliver the reliability and performance needed for critical applications across the country, backed by our local expertise and commitment to excellent customer service.
High Tensile Brass is an alloy based on copper, zinc, and a small but crucial addition of aluminum and sometimes iron. This specific composition is what gives the material its remarkable properties, primarily a high tensile strength and significant resistance to wear and corrosion. It is notably stronger than standard brass, offering excellent durability while remaining relatively easy to machine, making it a versatile and practical choice for engineers.

Yes, high tensile brass rods can be welded, but the process requires specific techniques. Methods like brazing or TIG welding are commonly used, with proper precautions to prevent zinc loss and cracking.
Yes, high tensile brass rods are highly suitable for machining. Their excellent machinability, durability, and resistance to wear make them ideal for precision components in industries like automotive, electrical, and plumbing.
High tensile brass rods offer excellent strength and moderate flexibility, making them bendable under controlled conditions. However, excessive force or improper techniques may cause cracking, so precision and care are essential.
The exceptional strength and wear resistance of these rods make them a go-to material in heavy-duty environments. They are widely used for manufacturing key marine components like propeller shafts, rudder bearings, and pump parts. Beyond the water, you’ll find them in high-stress industrial applications, including heavy machinery bushings, valve stems, and architectural fittings, where their ability to withstand constant stress and corrosive elements ensures long-lasting, dependable performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
