C70350 is an aluminium bronze alloy that comprises copper, aluminium, iron, and nickel. The alloy's composition offers excellent corrosion resistance, making it ideal for use in marine environments. This alloy also exhibits a high level of resistance to stress corrosion cracking, which results from exposure to chlorides and other corrosive agents, making it useful in environments where such exposure is common.
C70350 has several common applications, including use in pumps, bearings, valve components, and propellers. It is also suitable for gears and heat exchangers, especially where high corrosion resistance and thermal conductivity are required.
C70350 can be heat-treated for improved strength and wear resistance. Heat treatment also improves the alloy's machinability, making it easier to work with. Welding C70350 is also possible, but it requires preheating to avoid cracking, and post-weld heat treatment may also be necessary.
C70350 exhibits remarkable corrosion resistance, making it ideal for use in marine environments. However, it may react with certain acids and bases, leading to corrosion. As such, it is essential to consider the environment in which it will be used when selecting this alloy.
