Copper Alloys
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 is an alloy of copper that contains nickel and strengthening elements, such as iron or manganese. It is available in 90-10 and 70-30 compositions.

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 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.

Our evenness and consistency of chemical composition of our copper alloy products in mass production can be realised through continuous casting. We are able to supply copper alloy tubing exceeding 30 metres in length and can meet various customer demands. We can supply coils with weight range from 80-300kg per coil to meet the customers’ needs. The mill offers a high yield rate so the completion of large orders can be achieved easily. All of our tubing undergoes in-line eddy current detection to ensure the quality of our product.
