Copper Nickel Welding Rod

Cupro Nickel Tig Rod suppliers

Manufacturer of Copper Nickel Electrode, Cu-Ni Filler Rod and Cupro Nickel Brazing Rods

Sunflex Metal is one of the most respected suppliers of Cupro Nickel Welding Rods to the mechanical engineering industry in India. By the process of tig welding copper nickel to stainless steel, it gives the finest quality weld metal. These welding rods have a Density of 0.323 lb/in³ (8.94 g/cm3). The Yield Strength (annealed) of Cupro Nickel Electrode is 15000 psi (103 MPa). It has a Rockwell B Hardness of 69. Cupro Nickel Filler Rod is used a lot in leads of electronic components, transistor caps and anodes in electronic tubes. Such types of rods offer resistance against heat and acids. These rods offer better mechanical properties and better corrosion resistance.

These rods also have excellent resistance to biofouling and corrosion in seawater. Since over 50 years, Copper Nickel Tig Welding Rod are being used with great success in seawater. The Molecular Formula of Cupro Nickel Tig Rod is ‎CuNi. It has a Tensile Strength (annealed) of 52000 psi (359 MPa) and Tensile Strength (rolled-H04 for flat products/ hard drawn-H80 for tubing) of 78000 psi (538 MPa). Important to note that in the Copper Nickel Pipe welding procedure, most of the standard welding processes can be used to weld Copper Nickel. The Elongation at Break of Copper Nickel Brazing Rods (rolled-H04 for flat products/hard drawn-H80 for tubing), is 11.00% and its Elongation at Break (annealed), is 40%. These brazing rods have superior mechanical properties and they also have a perfect finish, without any flaws. Such rods have great strength and they also have an extended wear life. These types of rods can be readily fabricated and welded and as such they are a great choice for marine structures, heat exchangers and pipe systems.
