Based in Hamilton, New Zealand, Hemi Metals takes pride in being a trusted source for industrial-grade materials, with our Aluminium Bronze bars and rods standing as a testament to our commitment to quality. We understand that our customers rely on components that won’t let them down, which is why we focus on supplying this exceptionally durable and reliable copper alloy. For demanding projects right here in New Zealand and beyond, we provide the robust foundation that engineers and manufacturers count on for long-lasting performance in even the toughest working environments.
The specific composition of this alloy, primarily copper with significant aluminium, is what gives it such remarkable strength. It offers an excellent combination of high tensile strength and outstanding wear resistance, far surpassing many other non-ferrous metals. This material is also known for its impressive corrosion resistance, especially against seawater and various chemicals. These inherent mechanical properties make it a heavyweight champion for components that must endure constant friction, heavy loads, and exposure to harsh elements without failing.

To select the right aluminum bronze bar, consider factors like strength, corrosion resistance, wear resistance, temperature conditions, and alloy composition. Ensure compatibility with your specific application environment and mechanical requirements.
Aluminium bronze rods are available in various sizes, typically ranging from 1/8" to 6" in diameter. Finishes include as-forged, rough-turned, polished, and anodized for enhanced corrosion resistance.
Yes, aluminum bronze bars can be welded, typically using TIG or MIG welding methods. Preheating may be required to prevent cracking, and post-weld heat treatment helps ensure strength and integrity.
You’ll find Hemi Metals’ Aluminium Bronze bar and rod at work in some of the most challenging applications. It is the go-to material for heavy-duty bushings, bearings, and wear plates in the mining and marine industries, where its low friction and resistance to galling are invaluable. It’s also essential for manufacturing components like valve stems, pump parts, and gears, as well as in offshore engineering for fixtures that can withstand saltwater corrosion. Essentially, wherever strength and longevity are non-negotiable, this alloy proves its worth time and again.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
