Problems solved by technology

At present, the number and scope of high-strength aluminum alloys used in the industrial field are increasing, but the existing high-strength aluminum alloy materials are far from meeting the requirements of the industrial field
The existing high-strength aluminum alloy materials only meet some of the above conditions, and cannot meet all the above conditions at the same time, especially in terms of processing, surface quality, heat treatment, etc.
This also limits the use of high-strength aluminum alloy materials in the industrial field, affecting the use of high-strength aluminum alloys in the industrial field
In summary, aluminum alloy materials used in the industrial field generally require high strength, high toughness, high surface quality and various surface treatment capabilities. However, due to the high degree of aluminum alloying, it has difficulties in processing and forming, high heat treatment requirements, Poor surface quality and difficult surface treatment

The invention relates to an aluminum alloy material, and in particular relates to a high-strength aluminum alloy material. The aluminum alloy material provided by the invention comprises the following substances in percentage by weight: 0.1-0.4% of Si, 0.1-0.4% of Fe, 1.2-1.5% of Cu, 0.1-0.2% of Mn, 1.0-1.2% of Mg, 0.01-0.1% of Cr, 5.8-8.0% of Zn, 0.05-0.2% of Ti and the balance of Al and a small amount of inevitable impurities. According to the invention, an aluminum alloy material is introduced to meet the material performance requirement on high-strength aluminum alloy in current industrial fields, especially the performance requirements in processing and shaping, surface quality, heat treatment and the like.

Description

technical field [0001] The invention relates to aluminum alloy materials, in particular to a high-strength aluminum alloy material. Background technique [0002] Aluminum alloy materials are widely used in construction, civil and industrial fields. At present, there are many different requirements for industrial high-strength aluminum alloy materials, such as high strength, high toughness, good processing and forming properties, high corrosion resistance, various surface treatment properties or good heat treatment properties. At present, the number and scope of high-strength aluminum alloys used in the industrial field are increasing, but the existing high-strength aluminum alloy materials are far from meeting the requirements of the industrial field. Existing high-strength aluminum alloy materials only meet some of the above-mentioned conditions, and cannot satisfy all of the above-mentioned conditions at the same time, especially in terms of processing and forming, surfa...
