MANUFACTURER OF COPPER NICKEL ELECTRODE, CU-NI FILLER ROD AND CUPRO NICKEL BRAZING RODS

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.

Shielding gases are chosen taking Quality, cost, and Operability into consideration. Note: Both agglomerated and fused fluxes can be used for submerged arc welding. Note: The chemical composition of the flux mainly affects the chemistry of the weld metal and consequently its corrosion resistance and mechanical properties.
