6 Common Uses of Aluminum Bronze 

Aluminium Bronze 

Have you ever heard of aluminium bronze? It is an alloy of copper and aluminum, and it is incredibly strong and durable. It has been used in various industries, from aerospace engineering to shipping, for many years. This blog post will explore some of the many uses of aluminium bronze and how it can benefit businesses across various industries.

Uses of Aluminium Bronze

With a high intensity of anti-corrosive properties, aluminium bronze has become an increasingly popular material used by engineers. This alloy of copper and aluminum is able to withstand corrosive atmospheres as well as seawater, which has made it the perfect choice for many marine applications. In fact, many naval vessels such as ships and submarines are now being built using components made from aluminium bronze. Besides its use in naval engineering, aluminium bronze can also be found in other industrial settings, offering corrosion protection for parts that operate under extreme temperatures or that come into contact with harsh chemicals. From internal engine parts to power transmission gearboxes and even piping systems, this alloy is a widely sought after product due to its incredible strength and toughness.

Aerospace Engineering

Aluminium bronze is often used in the aerospace industry because it is incredibly lightweight yet very strong. This makes it ideal for use in aircraft components such as landing gear, engine mounts, and fuselage frames. Aluminium bronze also offers superior resistance to corrosion, which helps protect aircraft from rusting or corroding due to extreme weather conditions.

Marine Applications

This alloy has been used in marine applications for centuries due to its excellent resistance to saltwater corrosion. It is often used for propeller shafts, stern tubes, rudder stocks, and other boat parts that can withstand saltwater exposure without sustaining damage or corrosion. Aluminium bronze also provides superior wear resistance compared to other alloys making it ideal for ships that need reliable parts that can withstand long periods of time at sea without requiring frequent maintenance or repair.

Specialized Corrosive Resisting Applications

This alloy may often be used in violent, corrosive conditions which would normally be unacceptable for other copper alloys like brass. Bronze aluminum is also biofouling resistant in saline waters.

Seawater Applications

It is imbued with exceptional corrosion resistance in marine environments by the oxide film produced by aluminum bronze The material’s tolerance to wear and corrosion also allows it ideal for impellers, propellers and other maritime equipment.

Water Treatment Industries

The corrosion resistance of aluminum bronze may be a great value to components used in water treatment and service industries where corrosion is still a major concern.

Architectural applications

The amazing properties of bronze aluminum make it capable of withstanding heavy loads, shock and vibrational load. This makes the material ideal for bridge bearings and base insulating systems in seismic retrofitting buildings.

Manufacturing Components

Aluminium bronze is often used in the manufacturing industry because it can withstand high temperatures without being damaged or deformed. It is commonly used as a bearing material because it has excellent wear resistance and good thermal conductivity properties, which help maintain proper lubrication levels while preventing overheating during operation. Additionally, aluminium bronze offers superior machinability, which allows manufacturers to create precise components quickly and efficiently while reducing costs associated with production downtime due to errors or repairs.

Types of Aluminum Bronze

Numerous forms of aluminum bronze are classified in the Universal Numbering Scheme (UNS), established by the American Society for Testing and Materials (ASTM) and the Society of Automotive Engineers (SAE). These alloys differ primarily in terms of the amount of primary element (aluminum) and the number of secondary elements alloyed with the copper.

The different forms of bronze in aluminum are identified in the UNS using reference numbers from C95200 to C95800. C95200 aluminum bronze, for example, includes 8.5 to 9.5 per cent aluminum by weight, while C95300 comprises 9.0 to 11.0 per cent

While varieties of bronze alloys of aluminum are usable, they can all be grouped into four key types:

  1. Low alloy single-phase alloys — Such alloys produce less than 8% aluminum and have outstanding cold ductility properties, rendering them suitable for cold tubing, plates, sheets and wires.
  2. Moderately alloyed, two-phase (duplex) alloys — These alloys include 8 to 11 percent aluminum with minimal quantities of other elements incorporated for enhanced strength properties. Such fabrics are ideal for applications in hot working environments. The casting of aluminum bronze is also a common method of working such alloys.
  3. Copper-aluminum-silicon alloys, or bronzes with silicon-aluminum — These alloys include up to 6% aluminum and 2% silicone. As with other bronzes, these products have weak magnetic permeability and excellent shock and vibration resistance.
  4. Copper-manganese-aluminum alloys or manganese-aluminum bronzes — Unlike other aluminum bronzes, manganese is the main alloy ingredient by weight (about 13%) in such materials, whereas aluminum accounts for around 8% to 9%. Though these alloys do not have the same strength properties as the other forms, they have excellent impingement, cavitation and wear resistance.


Aluminium bronze is an incredibly versatile material that can be used in various industries, including aerospace engineering, marine applications, and manufacturing components. Its strength and durability make it ideal for creating reliable parts that can withstand extreme conditions without suffering damage or wearing out quickly. Its superior corrosion resistance also makes it an excellent choice for parts that need protection from saltwater or other corrosive elements. If your business requires strong yet lightweight components, then aluminium bronze may be the perfect solution!
