Aluminium bronze is a high-strength, corrosion-resistant copper alloy characterized by its distinctive golden color and excellent mechanical properties. It primarily comprises copper, with aluminium as the main alloying element, usually combined with other metals like iron or nickel to enhance specific traits. This alloy is valued for its robustness in harsh environments, including seawater and chemical exposure.
