UNS C77000 Copper Nickel Chemical Composition Properties, Grade, Tables and Document

The extreme conditions are the environment of submarine that contain two variable components of temperature and density, in which UNS C77000, a copper-nickel alloy, is known as having most remarkable corrosive resistance and thermal stability. Manufactured mainly of copper (Cu) and nickel (Ni) containing of 22% nickel is common. This alloy with corrosion resistance to seawater is another great example of such material that is widely used in marine field like building ships as well as offshore structures. Other important characteristics are heat conductivity and electrical conductivity that make it utilizable for either heat exchanging or electrical system. As the chemical composition of UNS C77000 is some other elements like the Fe and Mn in the very small quantities to improve the mechanical properties. In material standards documents, we are capable of defining detailed properties and composition tables, which may be useful for engineers and manufacturers when they are selecting the right materials for their specific applications.

UNS C77000 Copper Chemical Composition And Grade Table

UNS C77000 is a copper alloy with high performance, with major ingredients being copper (Cu) moreover nickel (Ni) and zinc (Zn). Its component of substances usually makes up about 58-63% of copper, 18-22% of nickel, and 18-22% of zinc. This alloy includes excellent corrosion resistant capabilities, especially in seawater, and it also displays satisfactory mechanical properties, which can be advantageous for several applications within the industry, like valves, pump components, and marine devices. C77000 has this reputation of being durable, easy to machine, and having great heat conductions, which gives it a niche market for the heavy duty industrial and marine applications.
