Talk to us if a standard alloy won't meet your requirements. Using our expertise and metal testing laboratory, we can work with you to make recommendations to design, manufacture and certify a custom alloy to meet your needs.
Our consistent, high-quality production standards stem from nearly a century of refined quality control processes. In our IANZ and ISO-17025 accredited laboratory, certified metallurgists utilise advanced instruments to test throughout the production process. You receive metal that meets your exact specifications, ensuring confidence in what you are purchasing and using in your project.

Copper products include various grades of brass, bronze, aluminium bronze, silicon bronze, copper-base master alloys, cupronickel, and minox. Our team will manufacture copper alloys to your specifications.
We manufacture a wide range of secondary aluminium alloys on-site and keep a comprehensive selection of standard primary aluminium alloys in stock to enable standard or specialist alloys to be produced to your needs.
We supply a wide range of white metals, including pewter, babbitt, bearing alloys, fusible solders, and ballast. We can manufacture and supply anything that you require.
Zinc alloys available include a range of zinc/aluminium alloys, toning alloy, ZP6 socketing alloy and anode zinc.
We manufacture a wide range of the highest quality leaded and non-leaded solders available on the market to suit your application.
We manufacture a range of lead alloys to support medical, traditional and industrial applications where the use of a non-leaded alternative is not suitable.
Foundry additions and pure metals are essential in manufacturing. Foundry additions improve the properties of molten metal, making it stronger and more durable.

The design of the artwork or the intended installation environment can often present challenges. Hayes Metals has the experience and expertise to collaborate with the artist or foundry to recommend the most suitable alloy or custom-tailor an alloy to meet the needs of all stakeholders, including the artist, foundry, and artwork owner.
Some of the equipment was situated in hard-to-reach areas, making a straightforward lift impractical. We employed our specialised equipment to construct rail tracks, enabling us to safely move the equipment from their locations to an area where we could then lift them using one of our crane trucks.
The project involved the decommissioning and removal of transmission towers in some very difficult locations, which required extensive planning and precise execution to ensure that neighbouring properties and buildings were not damaged.
