What is Aluminium Bronze?
Aluminium bronze is a family of copper-based alloys containing 5%–12% aluminium along with iron, nickel, or manganese to enhance strength, corrosion resistance, and fatigue performance. These alloys are renowned for their superior resistance to seawater, chemicals, high temperatures, and wear, making them a preferred choice for aggressive or abrasive environments.
