Aluminum bronze A copper-based alloy with aluminum as the main alloying element is called aluminum bronze. Aluminum bronze has higher mechanical properties than brass and tin bronze. The aluminum content of the practically applied aluminum bronze is between 5% and 12%, and the aluminum bronze with aluminum content of 5% to 7% has good plasticity and is suitable for cold processing.
When the aluminum content is greater than 7% to 8%, the strength increases, but the plasticity decreases sharply, so it is mostly used in the as-cast or after hot working. Aluminum bronze has higher wear resistance and corrosion resistance in the atmosphere, seawater, seawater carbonic acid and most organic acids than brass and tin bronze. Aluminum bronze can manufacture gears, shaft sleeves, worm gears and other high-strength anti-wear parts and high corrosion-resistant elastic components.
