Copper alloys such as copper nickel and brass offer superior resistance to corrosion in seawater. The products are mainly used in the marine industry, from seawater desalination plants to commercial shipbuilding. Other common uses include the aerospace industry, automotive industry, construction, refrigeration equipment and heat exchanger manufacturers.
Copper Nickel Tube
Copper nickel is an alloy of copper that contains nickel and strengthening elements, such as iron or manganese. It is available in 90-10 (90% copper, 10% nickel) and 70-30 (70% copper, 30% nickel) compositions.
The addition of nickel to the copper improves the strength and corrosion resistance without reducing ductility.
Brass is an alloy made of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties. We supply both aluminium brass and admiralty brass.
Admiralty brass: 69% copper, 30% zinc, 1% tin. It contains 1% tin to inhibit dezincification in many environments.
Aluminium brass: 77.5% copper, 20.5% zinc, 2% aluminium, 0.1% arsenic. It contains aluminium, which improves its corrosion resistance.
