ASTM B111 C71000 O61 copper-nickel Tubes for Heat Exchangers
O61 C71000 copper-nickel is C71000 copper-nickel in the O61 (annealed) temper. It has the second-lowest strength compared to the other variants of C71000 copper-nickel. The graph bars on the material properties cards below compare O61 C71000 copper-nickel to wrought copper-nickel (top), all copper alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
