Description

Extrusion casting aluminum alloy material and preparation method thereof
Technical Field
The invention belongs to the field of aluminum alloy materials, and particularly relates to an extrusion casting aluminum alloy material and a preparation method thereof.
background
The aluminum alloy is a multi-performance material which is beneficial to the light weight of equipment. By adjusting different element components, the aluminum alloy can respectively have different performances such as high heat conductivity, high electric conductivity, high yield strength, high tensile strength, corrosion resistance, high toughness, high hardness and the like. The method is widely applied to the fields of communication, automobiles, transportation, power, aerospace and the like. With the continuous development of science and technology, the requirements of high and new technology on materials are higher and higher. The single performance in the past can not meet the development requirement of the technology. The existing aluminum alloy material not only has strict requirements on the basic chemical components, but also needs to meet various special use requirements and has multiple properties. Some of these properties are even considered to be contradictory to each other in the past. Aiming at the use characteristics of different materials, various components and the performance thereof in the materials are reasonably prepared and optimized according to the specific requirements of the materials, so that the creation of a corresponding new aluminum alloy material is the objective requirement of the current and future development period.
ADC12 is a Japanese brand, also called 12 aluminum material, Al-Si-Cu series alloy, is an aluminum alloy which can be die cast and extrusion cast, and is suitable for cylinder cover covers, sensor supports, cylinder bodies and the like. It has good die casting performance and certain mechanical property, so that it is widely used in various common castings. However, since the die casting adopts a high-speed and high-pressure mode, the die casting is inevitably involved in gas, and the quality is affected. The extrusion casting is a low-speed high-pressure casting forming mode, and is characterized in that the air entrainment phenomenon in a die cavity during casting forming can be greatly reduced, the compactness of the casting is improved, and the quality of the casting is improved. It is a casting molding mode which can meet the high performance requirement. For higher mechanical property requirements, the existing ADC12 alloy can not meet the requirements by adopting a die casting or extrusion casting mode. Therefore, there is an urgent need for an aluminum alloy material which is superior to the ADC12 alloy in performance and can satisfy both thick-walled and thin-walled extrusion molding.
