Introduction to Aluminium Bronze
Aluminium bronze is a highly durable alloy, known for its excellent corrosion resistance and outstanding sliding properties. It is widely used in applications such as bearing surfaces and pistons, where both friction reduction and protection against harsh environments are critical. Composed mainly of copper and aluminium, this alloy provides long-lasting performance under heavy mechanical loads and in corrosive conditions, making it a reliable choice for industries that demand durability and smooth operation.
What is Aluminium Bronze?
Aluminium Bronze is an alloy that typically consists of 9-12% aluminium combined with copper, often with small amounts of other elements like iron or nickel. This combination gives the alloy its high strength, superior sliding properties, and excellent corrosion resistance. Aluminium bronze is particularly valued for its ability to form a protective oxide layer, shielding it from further oxidation and corrosion, which makes it ideal for harsh environments like marine, aviation, and industrial settings.
The primary advantage of aluminium bronze lies in its friction-reducing and wear-resistant properties, making it a top choice for components that require smooth operation and durability under mechanical stress, such as pistons, and bearings. While its corrosion resistance is an added benefit, especially in water-lubricated applications like ship shafts, its main strength is its performance in applications that demand low friction and long-lasting wear resistance.
Key Benefits of Aluminium Bronze
The primary advantages of aluminium bronze are:
- Outstanding sliding properties, reducing friction and enhancing durability in high-load applications.
- Good corrosion resistance, particularly in water-lubricated environments, such as those in the maritime sector.
- High strength and wear resistance, enabling it to withstand mechanical stress and maintain performance in demanding conditions.
While aluminium bronze offers good corrosion resistance, its true strength lies in applications where friction reduction and wear resistance are the main priorities. In cases where extreme corrosion resistance or specific wear properties are required, other materials may be more suitable.

What is Aluminium Bronze Used For?
Aluminium bronze is mainly used in industries that require excellent sliding properties as well as corrosion resistance, such as:
- Marine applications: Bearings and valve components in water-lubricated environments, such as ship shafts.
- Pistons and bearing surfaces: Where low friction and durability under mechanical stress are crucial.
- Water-lubricated bearings: Especially in sectors like maritime and offshore industries.
