Copper Nickel 95/5 Tube, designated as C70400, is an alloy composed of 95% copper and 5% nickel. This specific composition offers a combination of good mechanical properties and excellent corrosion resistance, particularly in marine environments.
The C70400 copper-nickel alloy is known for its excellent cold and hot workability and high resistance to brackish water, non-oxidizing acids, and seawater corrosion. These tubes are manufactured according to universal product quality standards using modern machinery and the latest technology at a well-equipped infrastructure. Quality control experts ensure that every product is of good quality, with no defects allowed.
Amardeep Steel supplies C70400 95-5 Copper-Nickel Tubes, known for their excellent properties. These tubes are either hot- or cold-worked to achieve the final size and are annealed when necessary to meet specific temper properties. The copper-nickel alloy used in these tubes has low resistivity and works well at temperatures up to 330°C. It is ideal for various applications due to its medium resistivity and low-temperature coefficient of resistance.
