These materials are recommended for use in pressure vessels, condensers, and heat exchangers. The materials are manufactured by either hot rolling or forging and finished by cold working and annealing to produce products of the required dimensions and properties. Tempers available under this specification are as hot rolled and hot rolled and annealed. The products manufactured for ASME Boiler and Pressure Vessel code applications must be certified to the hot rolled and annealed temper while all other products can either have hot rolled or hot rolled and annealed temper. This specification also contains information on the required material chemical compositions, densities, and tensile properties.

C70620

C70620 copper-nickel is a copper-nickel alloy formulated for primary forming into wrought products. The properties of C70620 copper-nickel include six common variations.
Copper-nickel alloys have excellent resistance to biofouling and marine corrosion, and possess good fabricability. Copper gains more strength and corrosion resistance when nickel is added to it.
This alloy possesses average high strength and good creep resistance at high temperatures, and costs more in comparison to copper-aluminum alloys and other alloys with similar mechanical properties.

Production flow

Production Flow

Anode casting wheel
The refined blister copper is poured into casting molds lined up side by side on the revolving circular table of a casting wheel and cast into anode plates for electrolytic refining. The anode plates are approximately 1m x 1m x 0.05m in size and weigh 380 kg per plate.

Refinery
Anode plates and stainless steel cathode plates are alternately set into the electrorefining cell, where a proper level of DC current is supplied. Dissolved copper from the anode is electrolytically deposited on the stainless steel cathode plate. After about 10 days of electrolysis, the cathode is lifted out and stripped from the stainless steel plate, resulting in the completion of refined copper (with a grade of 99.99%) as a final product. The refined copper is shipped in stacked bulks, which are 1m in length and width and approximately 80kg in weight.
