C71300 copper sheet is a high-performance copper-nickel alloy whose main composition contains 24.0-26.0% nickel (Ni+Co), as well as other minor elements. This material is known for its excellent mechanical properties and corrosion resistance, especially in seawater. In addition, C71300 copper sheet has a tensile strength of 94 ksi, a yield strength of 39 ksi, and a hardness of 180 HB, properties that make it ideal for use in the aerospace and marine industries, as well as the chemical industry.
In addition to its outstanding performance, C71300 copper sheet has good pressure processability in both hot and cold states, and can be fabricated into a variety of product forms, such as plates, rods, tubes, and strips, to suit the needs of different application scenarios. Due to its high strength and corrosion resistance, C71300 is widely used in the manufacture of parts that operate in steam and seawater environments, as well as critical components such as metal pipes and condenser tubes that operate under high temperature and pressure conditions.
