What is the difference between stretching aluminum and hot-rolled aluminum? What is the concept of stretching aluminum?
There is also a pre-stretched aluminum plate is relatively hard aluminum alloy (there are several grades), is in the production process to increase the stretch of this process, in order to eliminate the aluminum plate stress and strengthen the flatness of it.
Aluminum in the course of the use of a variety of processing methods: which are stretching, bending, stamping, cutting, etc. Tensile aluminum generally can not be too hard, too hard will pull the explosion, so the elongation of aluminum and anti- Tensile strength and so on according to the height of the drawing and the drawing method will have different requirements.Calculation and hot-rolled plate can be used for stretching, but the effect of casting plate is not ideal, so usually the stretch plate are generally Hot rolled plate.
The production process of aluminum plate is hot rolling, casting rolling, casting, etc., in which the aluminum plate made by hot rolling is superior to the aluminum produced by other processes in the aspects of stretching, oxidation and so on.With the cost of hot plate Production costs are relatively high.
Hot-rolled aluminum plate is the aluminum plate is the use of hot-rolled process produced by the aluminum plate, stretching aluminum is produced by the aluminum plate after stretching made of aluminum and aluminum parts.
