Copper is one of the oldest metals known to mankind, having been found and used by him centuries ago. Whilst there are several benefits of using pure copper, it is a very ductile metal, that could be alloyed with virtually any element. One such instance is the manufacture of Copper Nickel 70/30 Round Bars, which is the addition of about 30% nickel to a higher content of copper. Aside from grade 90/10 CuNi, this alloy is one of the most used ones.

Although available in an alloyed form, the ASME SB151 Copper Nickel 70/30 bar shares properties to both 90/10 CuNi as well as pure copper to some degree. However, because the metal has been alloyed, the level of a particular characteristic of the ASTM B151 Cupro Nickel 70/30 Flat bar will definitely differ from either of the former alloys. For instance, while the thermal and electrical conductive properties for both pure copper and 90/10 CuNi range between excellent and superior, these properties for the Copper Nickel 70/30 Round Bar would be good.

However, due to the increase in the quantity of nickel in its alloy, the metal will be useful in high-temperature environments. But using a higher content of nickel also means that the cost of the DIN 2.0882 Square bar will be higher because nickel is a commodity metal. Letting go of the fact that this alloy is higher priced, the use of Cu-Ni 70/30 Hex bar is seen in many areas of the engineering industry, though its utility is quite common in the manufacturing industry. For instance, the UNS No C71500 Rod could prove useful in several aspects of the shipping business.
