Funny story of Aluminium bronze

Funny story of Aluminium bronze
Aluminum bronze is the most worthy of attention as a structural material, as well as one of the most widely used in modern industrial copper alloy, because of the high strength, high hardness, good toughness and good wear resistance, corrosion resistance, and is widely used in the production of high load and high speed of corrosion wear parts, such as gear, valve, and large marine propeller, etc. It has higher corrosion resistance than brass and tin bronze in atmosphere, seawater, carbonic acid and most organic acids. However, the volume shrinkage of aluminum-bronze copper is higher than that of tin-bronze, and refractory alumina is easily produced inside the casting, which is difficult to be brazed and unstable in the superheated steam. Aluminum bronze is cheap and can be used as a partial substitute for some expensive metals, such as tin bronze, stainless steel and nickel-based alloys.
It was the British Navy in World War II who first used aluminum bronze as propeller material. Due to the use of aircraft engines in high-speed torpedo boats, the propeller speed is very high, the propeller made of high strength brass, has caused serious cavitation corrosion and corrosion fatigue, even difficult to maintain a voyage, from time to time there are dezincing, cracking and breaking accidents. To solve this problem, they chose Nickel aluminum bronze with better mechanical properties, corrosion resistance and cavitation corrosion resistance, and obtained good results.
