Based in the industrious city of Hamilton, Hemi Metals has forged a strong reputation as a leading manufacturer and supplier of high-quality aluminium forgings. We’ve built our business on a foundation of local expertise and a commitment to precision, producing components that are as reliable as they are robust. Our dedication to excellence ensures that our clients, both across New Zealand and internationally, receive superior forged solutions crafted to meet the most demanding specifications, supporting a wide range of critical industries with strength and integrity.
Our aluminium forgings are crafted from specific alloys known for their exceptional strength-to-weight ratio. This process of heating and pressing the metal creates a continuous grain flow, which significantly enhances its mechanical properties. The result is a component with superior toughness, excellent fatigue resistance, and reliable performance under high stress. These characteristics make our forgings far stronger than parts made by casting or machining from a solid block, offering unparalleled durability and longevity in the most challenging environments.

Yes, aluminium forgings can be shaped into custom designs using advanced forging techniques. Their excellent malleability and strength make them ideal for creating complex and precise shapes for various applications.
The ideal temperature range for aluminium forgings typically falls between 350°C to 520°C, depending on the alloy. This range ensures optimal malleability and prevents cracking during the forging process.
The forging process for aluminium typically takes a few minutes to an hour, depending on the complexity, size, and alloy type, along with required pre-heating and cooling times.
The applications for our aluminium forgings are incredibly diverse, spanning from the demanding aerospace sector to high-performance automotive and marine engineering. You’ll find our components in critical areas like suspension systems, aircraft fittings, and hydraulic piston rods, where failure is not an option. Their strength and light weight also make them ideal for heavy machinery, defence equipment, and specialised tools. Essentially, wherever a combination of lightness and immense strength is required to ensure safety and efficiency, Hemi Metals’ forgings provide a trusted and proven solution.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
