Abstract

The invention discloses a high-strength wear-resistant aluminum alloy material and a preparation method thereof, and relates to the field of aluminum alloy materials. Comprising the following raw materials in percentage by weight: 30-40% of metallic aluminum, 10-15% of metallic iron, 10-15% of metallic copper, 5-8% of metallic chromium, 5-8% of metallic manganese, 5-8% of metallic tin, 5-8% of metallic sodium, 5-8% of metallic magnesium, 1-2% of metallic silicon, 1-2% of metallic zirconium, 1-2% of metallic vanadium and 1-2% of metallic molybdenum. According to the high-strength wear-resistant aluminum alloy material and the preparation method thereof, aluminum, iron and copper serve as basic metal materials, chromium, manganese, tin and magnesium are added in cooperation, the density of the basic metal materials is improved, the rigidity strength and wear resistance of alloy are enhanced, active metal such as sodium, silicon, zirconium, vanadium and molybdenum is used in cooperation, and the high-strength wear-resistant aluminum alloy material is obtained. The alloy has good electric conductivity, heat conductivity, ductility and corrosion resistance.

Description

technical field [0001] The invention relates to the field of aluminum alloy materials, in particular to a high-strength wear-resistant aluminum alloy material and a preparation method thereof. Background technique [0002] The alloy formed by adding certain elements can have high strength while maintaining the advantages of pure aluminum such as light weight, which makes the specific strength better than many alloy steels, and becomes an ideal structural material, widely used in machinery manufacturing, transportation machinery, power In the machinery and aviation industry, the fuselage, skin, compressor, etc. of the aircraft are often made of aluminum alloy to reduce its own weight. Using aluminum alloy instead of welding of steel plate materials can reduce the structural weight by more than 50%. [0003] Aluminum alloy has low density, but relatively high strength, which is close to or exceeds high-quality steel. It has good plasticity and can be processed into various typ...
