C62400 Aluminium Bronze – Composition, Properties, and Uses

C62400 Aluminium Bronze

Bronze is one of the oldest metals known to humanity, and its use dates back to the Bronze Age. However, the use and importance of bronze have remained strong over time. In fact, it has evolved into various forms, and one such form is aluminium bronze. This blog post will discuss the properties, uses, and other important aspects of c62400 aluminium bronze.

C62400 Composition

C62400 aluminium bronze is a high-strength alloy that comprises around 81-85% copper, 6-8% aluminium, and 4-7% iron. It also contains smaller amounts of nickel, manganese, and tin. These elements impart excellent mechanical and physical properties to the alloy.

C62400 Uses

C62400 aluminium bronze has a wide range of applications in various industries. It is commonly used in the marine industry for making propellers, bearings, and other components that require high strength and corrosion resistance. It is also used in aerospace, oil and gas, power generation, and automotive industries for making bushings, gears, couplings, and valve bodies.

C62400 Corrosion Resistance

C62400 aluminium bronze has excellent corrosion resistance, making it suitable for harsh environments. It has good resistance to seawater, brine, and other corrosive fluids. It is also resistant to stress corrosion cracking and erosion-corrosion. These properties make it highly suitable for marine and offshore applications.

C62400 Heat Treatment

C62400 aluminium bronze is a heat-treatable alloy, and heat treatment can enhance its properties. The alloy can be annealed at 870-890 °C for 1-2 hours, followed by air cooling or water quenching. This treatment improves the alloy’s strength, ductility, and hardness.

C62400 Machining

C62400 aluminium bronze is easy to machine and can be machined with conventional techniques. However, due to its high strength and hardness, it can cause tool wear and breakage. Proper machining techniques, such as sharp cutting tools, slow speed, and high feeds, should be employed to avoid this.

C62400 Welding

C62400 aluminium bronze can be welded using TIG, MIG, and spot welding techniques. However, proper surface preparation and cleaning should be done before welding to prevent contamination. Preheating may also be required to avoid cracking.


C62400 aluminium bronze is a high-strength, corrosion-resistant alloy with various industrial applications. Its excellent mechanical and physical properties make it ideal for harsh environments such as marine and offshore. Its heat-treatable and easy-to-machine properties make it popular for components like bushings, bearings, gears, and valve bodies.
