Copper Tube 1/4 inch Pancake Coil Copper Pipe For Air Conditioner Copper
We have of sales offices in most major centres in India. Copper Nickel Alloy Tube also knowns as Cupro Nickel Tube or Cuni Tubing, it has a Tensile Strength (annealed) of 52000 psi (359 MPa) and it has a Tensile Strength (rolled-H04 for flat products/ hard drawn-H80 for tubing) of 78000 psi (538 MPa). Alloy of copper and nickel is called Copper Nickel tubing and it has very high resistance to corrosion in seawater. Though cuni finned tubing has similar corrosion resistance to that of copper, it has better fatigue strength and superior general strength. Because of its characteristics, such Cupro Nickel Seamless Tube is used in offshore fire water systems, evaporators used in power stations, cabled tubes for pneumatic lines and hydraulic lines and in cylinder cores in high-quality locks.
The Thermal Expansion Co-efficient of Copper Nickel Seamless Tubing (@20-300°C/68-572°F) is 9.00 µin/in °F (16.2 µm/m °C). Cu-Ni Tubes has an Elastic Modulus (C71500 annealed) of 22000 ksi (152 GPa). Copper nickel alloy tube chemical composition is Cu 71.25-76.5, Fe ≤ 0.20, Pb ≤0.050, Mn ≤ 1.0, Ni 23.5-26.5 and Zn ≤ 1.0. Copper Nickel Welded Tube has a Thermal Conductivity of 32.9 W/mK (0.0900 BTU in/hr.ft². °F) and it has a Rockwell B Hardness of 69. ASME SB466 Cupro Nickel Tube has superb formability, making for ease of bending and flaring. It offers trouble-free installation, longer life and it exhibits characteristics of reliability and safety. In the 19th century, jackets of bullets were coated with Copper nickel. At low temperatures, it has excellent thermal conductivity and as such it is used in a wide number of cryogenic applications. It is also used in heat exchangers, fasteners, feedwater heaters, silver-colored circulation coins, jewelry and in boat hulls.
