Introduction
Aluminum bronze is essentially a brass, a mixture of copper with up to 15% of aluminum. This metal is incredibly strong and resistant to corrosion. Though aluminum bronze is one of the most expensive bronze alloys, the advantages it provides make it an ideal metal for bearing and other applications.
Characteristics
Aluminum bronze is a high strength alloy, it is stronger than plain bronze and brass alloys. This strength and stiffness make aluminum bronze a good choice for bearing applications as it can take on a greater load than other more commonly used alloys.
Aluminum bronze alloys are also resistant to corrosion, even in aggressive liquids. They resist sea water, hot and cold water, and even some acids. The combination of aluminum and copper creates a protective oxide layer that wards off corrosion and improves longevity.
The ductility of aluminum bronze is also impressive. This is what allows the alloy to be formed, hammered and machined. As a result, aluminum bronze makes an ideal choice for a number of applications from tubing and gearwheels to bearings, hinges and propellers.
Applications
Aluminum bronze alloys are incredibly versatile and as a result have a number of different uses. They can be used in sea and land vehicles, as well as in areas such as railway, construction and industry.
Some common applications for aluminum bronze include:
• Automotive and Aerospace Industry: Aluminum bronze is often used in aircraft and missiles to provide strength and endurance. It is also used in the automotive industry to make piston heads, engine bearings and shafts that require a high degree of strength and reliability.
• Marine Industry: Due to its corrosion resistance and impressive strength, aluminum bronze is often used to construct propellers, shafts, bushings and pumps.
• Food Processing: Aluminum bronze is often used in food contact products. It resists corrosion, even when exposed to acidic foods, and its non-toxic nature makes it ideal for kitchen utensils and food containers.
Conclusion
Aluminum bronze is an ideal alloy for a number of applications due to its impressive strength and corrosion resistance. While it is one of the more expensive bronze alloys, the advantages it provides make it a great choice for marine, aerospace and food processing industries. With its high ductility, aluminum bronze can be used for a variety of applications from bearings and bushings to propellers and motors.
