As a leading manufacturer & supplier of quality Copper Nickel Compression Fittings since 1990, we have forged a name for ourselves in this challenging sector by focusing on our client needs. Copper Nickel Hydraulic Fittings applications are many, as they are widely used all over the world, because of the very high resistance that these Copper Nickel ferrule Fittings display towards seawater. Cuni 90 / 10 Compression Fittings has a Thermal Conductivity of 32.9 W/mK (0.0900 BTU in/hr.ft². °F). The Thermal Expansion Co-efficient of Cupro Nikel Male Connector NPT MCN (@20-300°C/68-572°F) is 9.00 µin/in °F (16.2 µm/m °C). Cu-Ni Male Connector NPT MMCN has a Shear Modulus (C71500 annealed) of 8300 ksi (57.2 GPa). Copper Nikel Male Bulkhead Connector has a Density of 0.323 lb/in³ (8.94 g/cm3).
These fittings 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). In seawater, Copper Equal Compression Tee Pipe Fittings display superior resistance to corrosion. Copper nickel 70/30 Male Fittings consists of 70% copper and 30% nickel alloy, to which manganese and iron have been added. They can easily be fabricated and cold worked. Copper Nickel Ferrule Tube Fittings has a Rockwell B Hardness of 69. The Chemical Composition of Cupro Nickel Male Elbow NPT is Cu 71.25-76.5, Fe ≤ 0.20, Pb ≤0.050, Mn ≤ 1.0, Ni 23.5-26.5 and Zn ≤ 1.0. Cupro Nickel Male Branch Tee has an Elastic Modulus (C71500 annealed) of 22000 ksi (152 GPa). Copper Nickel 90 / 10 Ferrule Tube Fittings have an alpha – phase structure. Wherever there are liquids in any kind of piping system, at some time or the other, leaks are bounds to start taking place. At such a time, so as to prevent the leak from worsening, the ideal thing to be done, would be to employ the use of compression fittings made from Copper Nickel.
