Product Type:heat exchanger cuni tube
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. | Trade Name | UNS | Copper Nickel Industry Specifications | Chemical Composition | Min.Tensile
