Technical purpose and operational characteristics
The ASTM B372 standard regulates the production and supply of high-precision seamless rectangular waveguide tubes made of copper alloys grades UNS C10200, C10300, C12000, and C22000. Products supplied by EV Group China are optimized for integration into modern high-frequency data transmission systems and specialized electrical equipment, where the stability of geometric parameters and material conductivity are critical.
Requirements for composition and physical-mechanical properties
To ensure signal transmission reliability in waveguide paths, grades C10200, C10300, and C12000 undergo strict control for the absence of copper oxide. Quality control includes mandatory tests for embrittlement in a reducing atmosphere, as well as measurements of electrical resistivity, the parameters of which must strictly correspond to ASTM engineering tolerances. EV Group China’s technological control guarantees that the material meets the stated physical characteristics for operation in complex electromagnetic environments.
