This specification covers seamless copper and copper-alloy rectangular waveguide tube intended for use as transmission lines in electronic equipment. Four types of material are specified having the following nominal compositions: C10200, C10300, C12000, and C22000. The copper and copper-alloy tubes shall be finished by such cold-working and annealing operations as are necessary to meet the required properties. The material shall conform to the chemical requirements specified. The material shall conform to the Rockwell hardness requirements prescribed. The test specimens of copper UNS nos. C10200, C10300, and C12000 shall be free of cuprous oxide. It is to be expected that samples of Copper UNS Nos. C10200, C10300, and C12000 shall be capable of passing the embrittlement test. It is to be expected that samples of copper UNS nos. C10200, C10300, and C12000 will conform to the prescribed electrical resistivity requirements. Samples for chemical analysis shall be taken accordingly.
