From the heart of Hamilton, New Zealand, Hemi Metals proudly manufactures and supplies a cornerstone of engineering: Brass Rod Grade 1. Known for its excellent combination of strength and ductility, this particular brass alloy is a reliable favourite for a wide range of projects. We ensure every rod meets the highest standards, providing machinists, engineers, and creators across New Zealand with a consistent, high-quality material they can trust to perform from the very first cut to the final product.
Brass Rod Grade 1 is primarily composed of around 65% copper and 35% zinc, a classic combination that gives it a distinctive bright golden appearance. This specific balance delivers a superb blend of mechanical properties, offering good tensile strength alongside remarkable malleability. It machines beautifully with minimal tool wear, producing clean, short chips. Its inherent corrosion resistance makes it a dependable choice for many environments, and it can be easily soldered and brazed for secure, lasting joins in various assemblies.

Yes, Brass Rod Grade 1 can be welded, but it requires special care due to its high zinc content. Proper technique and filler material are essential to prevent zinc evaporation and porosity.
Yes, Brass Rod Grade 1 is highly suitable for machining due to its excellent machinability. It allows easy cutting, threading, and shaping, making it ideal for precision parts and components.
The hardness of Brass Rod Grade 1 typically ranges between 60-100 HRB (Hardness Rockwell B), depending on the exact composition and temper of the material.
The versatility of Brass Rod Grade 1 makes it a common sight in workshops everywhere. It’s the ideal choice for crafting durable machined components like gears, locks, and architectural hardware. Plumbers and marine engineers frequently use it for fittings, valves, and nuts due to its resistance to water corrosion. You’ll also find it in everyday electrical components, musical instruments, and decorative turnings. Essentially, any project that demands a strong, corrosion-resistant, and easily worked metal is a perfect fit for this dependable brass rod.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
