Aluminum Alloy Decorative Strip

As a lightweight metal material with excellent performance, aluminum alloy decorative strip is widely used in the fields of construction, machinery, electronics and automobile. The increase in application fields also puts forward higher requirements for the protective performance and decorative effect of the aluminum alloy strip surface. The production process of the aluminum alloy strip mainly includes three processes: casting, extrusion and coloring. Among them, the coloring mainly includes: oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, wood grain transfer and other processes.

A preparation method of aluminum alloy decorative strip. The preparation method first smelts electrolytic aluminum liquid, aluminum ingots and aluminum alloy solid waste into aluminum melt, and then prepares 3 to 5 mm thick aluminum coils through continuous casting and rolling, and then After cold rolling, intermediate annealing, cold rolling→cleaning and trimming→finished annealing→stretching and rewinding→checking the packaging process, 0.7~1.0mm thick aluminum strip for decoration is prepared. The tensile strength of the aluminum alloy strip can reach 220~240Mpa, and the elongation rate ≥10% and 90° bending without cracking, which shortens the process flow and reduces the production cost.

The aluminum alloy decorative strip product is made of high-strength aluminum alloy material in grades of 1000 series, 3000 series, 5000 series and 8000 series. The aluminum alloy strip should have beautiful surface, clean edge, in addition, the aluminum decorative strip is often treated by overall electrostatic spraying. The appearance is beautiful, wear-resistant and easy to clean; the structure is reliable and generous, and it is durable.
