From the heart of Hamilton, New Zealand, Hemi Metals stands as a dedicated manufacturer and supplier of precision-engineered aluminium components. We take particular pride in our expertise with Aluminium 5083 Forgings, producing parts that meet the rigorous demands of industries where failure is not an option. Our local production ensures quality you can trust and service you can depend on, providing robust solutions forged with Kiwi ingenuity for both domestic and international clients who require exceptional strength and resilience.
The composition of Aluminium 5083 is renowned for its magnesium core, which is the secret to its impressive strength. This alloy is further fortified with manganese and chromium, creating a material that is not only exceptionally strong but also highly resistant to corrosion, especially in marine environments. Through the forging process, we enhance these inherent qualities, refining the grain structure to achieve superior mechanical properties, including excellent toughness and an outstanding strength-to-weight ratio that performs reliably under stress.
