Description

technical field [0001] The invention relates to the technical field of aluminum alloy materials, in particular to a high-strength wear-resistant aluminum alloy material for doors and windows and a heat treatment process thereof. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in the industry. It is widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. Aluminum alloy has low density but high strength. Deformed aluminum alloys and cast aluminum alloys are divided into two categories. Deformed aluminum alloys can be processed under pressure and can be processed into various shapes and specifications of aluminum alloy materials. They are mainly used in the manufacture of aviation equipment, building doors and windows, etc. Heat-treatable-strengthened aluminum alloys and heat-treatable-strengthened aluminum alloys; cast aluminum alloys can be divided into aluminum-s...
