Aluminium Bronze

C63000 / C63200

One of the American grades of nickel aluminium bronze. Containing around 10% aluminium, 5% nickel and 3% iron the alloy offers an inherent high strength and hardness combined with a very good toughness and an excellent resistance to wear, shock and abrasion.

Offers very good corrosion and erosion and cavitation resistance in seawater and non-oxidising acids. It also has a very good galling resistance and also offers a high retention of mechanical properties at elevated temperatures making this ideal for aerospace applications. Used typically in the Oil and Gas and Marine environments.

C63200 is a strong, corrosion resistant material that performs well at high and low temperatures. It also has a low magnetic permeability, making it ideal for use on instrumentation systems, seawater piping systems and marine propulsion units.

• Aluminium is the main alloying metal added to copper in contrast to standard bronze (copper/tin)
• Higher strength and corrosion resistance compared to other bronzes
• Resistance to corrosion in seawater
• Material reacts with atmospheric oxygen to create a tough layer of aluminium oxide
• Commonly used in the marine sector, oil and petrochemical industries (non sparking environments)
• Used in the manufacture of valves and fasteners
