Abstract

The invention relates to an aluminum alloy material and a surface treatment method thereof. The aluminum alloy material respectively comprises the following components: lithium, zinc, copper, silicon, manganese, magnesium, titanium, boron, germanium, molybdenum and the balance of aluminum. The surface treatment method of the aluminum alloy material comprises the following steps: (1) removing a surface oxidation film of the aluminum alloy material; and (2) carrying out chemical plating on the aluminum alloy material obtained from the step (1). The aluminum alloy material disclosed by the invention can be used for integrally enhancing various aspects of properties of the aluminum alloy material, enhancing the mechanical strength and tensile property of an aluminum alloy and enhancing the tensile strength, yield limit and heat resistant property of the aluminum alloy material. The surface treatment method disclosed by the invention is conductive to improving the surface stability of the aluminum alloy, thereby achieving more brightness and good beauty of the surface of the aluminum alloy material.

Description

technical field [0001] The invention relates to an aluminum alloy material and a surface treatment method thereof, and belongs to the technical field of processing metal materials and metal materials. Background technique [0002] Aluminum is a pure white light metal with ductility, and its products are often made into rods, sheets, foils, powders, ribbons and filaments. In humid air, an oxide film can be formed to prevent metal corrosion. Aluminum powder and foil burn violently when heated in the air, emitting a blinding white flame. Soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, insoluble in water. The content of aluminum in the earth's crust is second only to oxygen and silicon, ranking third, and is the most abundant metal element in the earth's crust. The development of the three important industries of aviation, construction, and automobile requires that the material properties have the unique p...
