Farmers Copper LTD. maintains an extensive inventory of Copper Nickel C706 in bar, plate & sheet, tube, pipe, fittings, and flanges. Copper Nickel C706 is also known as Copper Nickel 90/10 because it is made up of 10% nickel or as ASTM B466 and ASME SB466. C706 is known for its moderate strength, weldability, and formability. The inclusion of controlled quantities of iron and manganese also give the 90/10 alloy an extraordinary resistance to general corrosion and stress cracking, as well as to erosion and impingement due to turbulent water containing air bubbles and silt flowing at high velocities. If you don’t see the material that meets all of your requirements, give us a call or request a quote and we will see what we can do for you.
