Nestled in the hardworking city of Hamilton, Will Sheetsandplates takes pride in being a trusted local source for industrial metals, with a particular expertise in the exceptional Aluminium Bronze Circle. We understand that the right material is the foundation of any great project, which is why we supply these high-performance discs to the craftsmen, engineers, and innovators across New Zealand who demand resilience and reliability. It’s our way of supporting local industry with quality products you can count on, right from our own backyard.
The strength of Aluminium Bronze lies in its unique composition, primarily copper alloyed with a significant amount of aluminium, often with additions of iron and nickel. This blend gives the material a remarkable set of mechanical properties, including very high strength, excellent wear resistance, and an outstanding ability to withstand corrosion, especially in seawater and acidic environments. It’s a tough, long-lasting metal that performs reliably under heavy loads and challenging conditions where other materials might fail.
