Stretching is one of the processing methods of aluminum brazing sheet plate. Stretching aluminum plate is produced by stretching the aluminum and aluminum fittings made after, but the tensile aluminum plate generally can not be too hard, too hard will pull the explosion, so the Elongation and tensile strength of aluminum alloy sheet, etc. Depending on the stretch-height and stretch method will have different requirements, 5052 aluminum alloy plate often need to be stretched during use.
In addition to pay attention to the tensile height of 5052 aluminum plate, its own hardness, but also need pay attention to their own performance, the product to achieve the best results, their performance can not be damaged in the process of stretching, to give full play to the product Performance advantages.
Precautions for aluminum sheet drawing process:
Tensile aluminum plate is produced in the implementation of aluminum stretching technology, the use of processing, there is an increase in the production process of stretching this process is to eliminate the internal stress of aluminum and enhance the flatness, which is called pre-pull Stretch, suitable for high hardness aluminum alloys, 5052 aluminum aluminum plate in the production process in order to increase the flatness will use the pre-stretching technology, but to the hardness range. Casting and hot rolled aluminum plate can be used for stretching, but the effect of cast rolled aluminum plate is not ideal, so commonly referred to as the hot rolled aluminum plates are generally.
