Description

[0001] technical field [0002] The invention relates to an alloy material, in particular to an aluminum alloy material and a method for manufacturing double-zero foil with it. Background technique [0003] Aluminum foil meets various needs of modern production in a wide range of fields with its unique properties. With the development of economy and technology, the requirements for the quality of aluminum foil are increasing day by day. It is hoped that the thickness of aluminum foil will be thinner, with fewer pinholes, and higher mechanical properties and surface quality. [0004] At present, most double-zero aluminum foils use 1235 alloy or 8079 alloy. Due to the low total element content of 1235 alloy, the mechanical properties of the finished double-zero foil are low, which cannot meet the production requirements of modern high-speed compound machines; while 8079 double-zero foil Due to its high mechanical properties, it meets the needs of high-speed composite machines...
