From the heart of Hamilton, New Zealand, Hemi Metals stands as a dedicated manufacturer and supplier, bringing local expertise and global standards to the forefront. We specialise in producing high-quality Aluminium 5754 Forgings, crafted with precision to meet the demanding needs of various industries. Our commitment lies in delivering components that offer exceptional strength and reliability, supporting New Zealand’s manufacturing sector with robust, locally-made solutions that you can count on for critical applications.
The composition of Aluminium 5754 is primarily aluminium with a significant addition of magnesium, which is the key to its excellent strength. This alloy is known for its superb corrosion resistance, especially in marine environments, and offers good weldability. Through the forging process, we enhance its mechanical properties, resulting in a final product with superior toughness and structural integrity, making it a reliable choice where performance under stress is non-negotiable.

Aluminum 5754 has excellent workability, making it easy to forge. Its good formability allows for intricate shapes, but requires careful temperature control to prevent cracking and ensure quality.
Aluminum 5754 offers excellent corrosion resistance, high strength, good weldability, and formability. It's lightweight, resistant to stress corrosion cracking, and performs well in marine and industrial environments.
The forging process for Aluminium 5754 typically takes a few hours to a day, depending on the complexity, size, and type of forging, including heating, shaping, and cooling stages.
You’ll find our Aluminium 5754 Forgings hard at work in some of the most challenging settings. They are essential in marine engineering for components like boat fittings and deck hardware, and in the automotive sector for strong, lightweight parts. Their resistance to corrosion also makes them ideal for chemical handling equipment and various architectural applications. Essentially, wherever a combination of strength, light weight, and durability against the elements is required, these forgings provide a trusted and effective solution.
