Abstract

The invention relates to the technical field of aluminum alloy performance research and discloses an aluminum alloy door and window material with the excellent sound-insulation effect. By blending thealloy proportion, the aluminum alloy door and window material has excellent mechanical and chemical performance, a porous additive is added as a modifier, the aluminum alloy door and window materialis refined and fused, then an aluminum alloy is full of the aluminum alloy door and window material, thus the structure of the aluminum alloy is changed, the porous structure with the great sound-insulation effect is formed, ambient noise can be prevented from entering an isolation space, and the life quality of people is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy performance research, and in particular relates to an aluminum alloy door and window material with excellent sound insulation effect. Background technique [0002] Aluminum alloy usually uses alloying elements such as copper, zinc, manganese, silicon, magnesium, etc. Compared with ordinary carbon steel, it is lighter and has corrosion resistance, but its corrosion resistance is not as good as that of pure aluminum. A protective oxide layer forms on the surface of aluminum alloys in a clean, dry environment. Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, aluminum alloy and chemical industry. Because of their good physical and chemical properties, aluminum and aluminum alloys have been widely used in marine industry, power system and aviation and othe...
