Aluminum alloy composite plate made of electronic product and its manufacturing method

摘要

Problem to be solved: to provide an aluminum alloy composite plate and a method of manufacturing the same.Solution: the first type aluminum alloy plate 10 and the second aluminum alloy plate 20, which are made of a composite plate, are laminated together.Aluminum alloy plate and second type aluminum alloy plate are superimposed through hot rolling process.An aluminum alloy composite plate P having a three-layer structure is provided.Subsequently, the aluminum alloy composite plate is thinner rolled from the thick to the required thickness by the cold rolling processFurther, it becomes an aluminum alloy composite plate with good press forming performance through a t treatment process and an anodization process.Aluminum alloy plate and second type aluminum alloy plate are selected from different aluminum alloy materials.The first type aluminum alloy plate is provided as an intermediate layer of the aluminum alloy composite plate to provide the mechanical strength necessary for the electronic product housing.As the outer layer of aluminum alloy composite plate suitable for anodizing and dyeing treatment of type 2 aluminum alloy plateMeets the demands for appearance beautification of electronic product housing.Diagram
