Description

technical field [0001] The invention belongs to the technical field of aluminum alloy plate manufacturing, and in particular relates to a 6M61 aluminum alloy base material for a 5G filter cover plate and a preparation process thereof. Background technique [0002] As a frequency selective device, cavity filters are widely used in the field of communication, especially in the field of 5G radio frequency communication. In the base station, the filter is used to select the communication signal and filter out the clutter or interference signal outside the frequency of the communication signal. The cavity filter includes the cavity, the cover plate, the inner / outer conductor of the connector, etc. In order to ensure the precision of the cavity shell, the aluminum material used is required to have good rigidity, non-magnetic, machinability, and good heat dissipation. In particular, good heat dissipation can reduce the influence of temperature changes on the structure of the filte...
