The mass production of CuCrZr alloy - ITER Grade tubes for the ITER divertor outer vertical target (OVT) prototype and series production is now in progress as well as other material. It is required to manufacture the CuCrZr tube with the mechanical properties required by the design and with the grain growth suppressed in terms of prevention of water leakage and durability of electromagnetic load even after the completion of the OVT. Therefore, the mechanical properties are tested prior to a use for the OVT to confirm the mechanical properties and the quality during mass production of the CuCrZr tube. This paper reports the tensile properties, which are one of important mechanical properties required for the CuCrZr tubes used in the prototype and series production of the OVT. As the results of sampling inspection during the mass production, the CuCrZr tube was capable of meeting required values of the tensile properties even after the heat treatment simulated the solution annealing and aging in the PFU manufacturing.
