Description
Technical field
The present invention relates to a kind of aluminum veneer cast alloy material, with and preparation method thereof, belong to aluminum alloy materials and manufacture field.
Background technology
Industrial, construction material aluminum veneer is Al-Mn alloy frequently with 3, belonging to the wrought aluminium alloy that heat treatment can not be strengthened, such material has the excellent combination properties such as lightweight, moderate strength, plasticity height, strong, any surface finish of extension good processability, good welding performance, corrosion resistance. Wherein representative is 3003Al-Mn alloy, because which are added Mn element so that height wanted by its intensity and hardness ratio fine aluminium, is widely used in the aspect such as container, architectural constructional materials.
Mn is the main component in Al-Mn alloy, and content is between 1.0% ~ 1.6%, and too high levels can affect the performances such as casting and the calendering of alloy, too low, and mechanical property is reduced. But due to the existence of Mn, easily produce segregation when casting cooling, cause that the performance of alloy reduces. Inevitably there is Fe element in Al-Mn alloy, Fe dissolves in MnAl6Middle formation (FeMn) Al6, it is the impurity phase in alloy, and matter is hard and crisp, can subtract low-alloyed mechanical property, which limits the application that this is alloy. Meanwhile, along with the continuous extension of industry and adnornment industry, traditional Al-Mn alloy strength is on the low side, can not meet requirement. At present, the research of Al-Mn system alloy is concentrated mainly in improvement casting method and processing technique, improves alloy microstructure with this, improve mechanical property. Although the research of Al-Mn alloy being achieved some achievements, but these researchs focusing mostly in improving a certain performance of alloy by local process, still there is the problems such as intensity is relatively low. In order to improve the intensity of Al-Mn alloy, researcher adds multiple alloying element in the alloy, such as Cu, Fe, Si, Mg, Zn etc. But, do so makes the production cost of alloy improve on the one hand, on the other hand, can not coordinate very well between intensity level with plasticity so that processing characteristics worsens, there is alloy while improving some performance, there is the contradiction declined in other performances, and are not suitable for commercial production. It is desirable in the mechanical property keeping improving further on the basis of good processing characteristics material, this can play the effect reducing scantling and weight, reduces the production cost of material.
