This specification establishes requirements for copper-beryllium alloy seamless tube in straight lengths. The material of manufacture shall be Copper Alloy UNS C17200, cast and worked into tubular form that shall have heat traceable identity. The product shall be manufactured by a combination of hot and cold working, annealing, or precipitation heat treatment, or both, as to produce a uniform wrought structure in the finished product, to meet the temper specified (TB00 (A), TD04 (H), TF00 (AT), or TH04 (HT)). The material shall conform to the chemical composition requirements prescribed for beryllium, copper, aluminum, silicon, and additive elements such as nickel, cobalt, and iron, as determined by chemical analysis. The alloy shall also conform to the specified physical property requirements such as microstructure and grain size, and to the prescribed dimensional and mass requirements. The material shall meet the requirements specified for mechanical properties before and after precipitation heat treatment, such as Rockwell hardness, tensile strength, yield strength, and elongation. Requirements for tension test and other tests to be used to determine the properties mentioned including sampling and specimen preparation are detailed.
