We use advanced technology to produce copper clad aluminuml sheet, which has a wide range of applications in the field of power and decoration.
Bimetallic composite is a hotspot in material research because it integrates the excellent properties of various matrix metals and makes up for the deficiency of single metal． As a typical bimetallic composite，Cu / Al bimetallic composite comprehensively utilizes the advantages of high conductivity and heat conduction of copper，as well as light weight，easy welding and low cost of aluminum，which is widely used in electric power，heat transmission，automobile and other fields，attracting extensive attentions of researchers at home and abroad．
However，the main difficulties in preparing Cu / Al bimetallic composites include: ( 1) both copper and aluminum materials are easy to be oxidized，and the formed oxidation film is difficult to be removed; ( 2) the interface is easy to form hard and brittle intermetallic compounds，which
will harm the performance of Cu / Al bimetallic composites． Therefore，in recent years，researchers have made a lot of researches including how to improve the existing processes and develop new processes; exploring the interface formation mechanism，growth regulation of intermetallic compounds，size and performance matching between component metals，deformation and heat treatment coordination，performance characterization and other aspects．
The growth of intermetallic compounds is controlled by optimizing process parameters and physical and chemical methods to improve interfacial bonding strength． In-situ characterization is used to observe the phase evolution of the interface and explore the interface bonding mechanism．Combined with the finite element simulation technology，the research on deformation，heat treatment and defect prediction of Cu / Al bimetallic composite is carried out to guide the actual production． The mechanical，electrical，thermal and corrosion resistance properties of Cu / Al bimetallic composites are evaluated comprehensively，and their application potential is explored continuously．
