Based in the heart of Hamilton, New Zealand, Hemi Metals is a trusted local source for high-quality aluminium bar and rod, providing a reliable foundation for innovation and construction across the country. We understand that your projects demand materials you can count on, which is why we are committed to supplying a consistent and durable product. Our focus is on delivering not just metal, but a key component for builders, engineers, and creators who are shaping the future of our industries right here in Aotearoa.
Our aluminium bar and rod are known for their excellent blend of strength and lightness, a characteristic of the high-grade alloys we select. This material offers impressive mechanical properties, including good tensile strength and excellent corrosion resistance, allowing it to withstand challenging environments without becoming brittle. It’s also highly malleable, making it exceptionally easy to machine, cut, and fabricate into precise components, which streamlines the manufacturing process from our facility to your workshop.

Yes, aluminum bars are corrosion-resistant due to the formation of a natural oxide layer on the surface, which protects them from rust and deterioration, especially in various environmental conditions.
Yes, aluminum rods can be customized in size and length according to specific requirements. Manufacturers can cut, shape, and tailor the rods to meet precise specifications for various applications.
Aluminium bars perform poorly in high-temperature environments, as they lose strength and can soften at temperatures above 150-200°C. They are prone to oxidation and are unsuitable for extreme heat applications.
From intricate machined parts in advanced robotics to robust structural frames in architectural designs, the applications for our aluminium bar and rod are nearly limitless. They are a go-to material for engineering projects, automotive components, and custom fabrications where reducing weight without sacrificing integrity is crucial. Whether you’re crafting specialized tools, constructing marine fittings, or creating artistic installations, this versatile material provides the perfect balance of workability and enduring performance that so many Kiwi projects require.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
