Coated aluminum coil is a classification of aluminum coil, and it is also a commonly used one. Although people often use it and often see it, they do not know how it is produced,let me share with you the two production methods of this product and the differences between the two methods.
The production methods of this product can be divided into two types: cold rolling and hot rolling. The main difference between the two methods is whether anodizing can be done.The hot rolling method can be anodized. Its characteristic is that in the process of large plastic deformation, the internal structure undergoes multiple recovery and recrystallization, and the coarse grains in the casting state are broken.The micro-cracks heal, so that the internal structure of the billet is homogenized, the size and shape of the grains, the concentration of point defects and line defects and other casting defects have been significantly improved, so that the as-cast structure is transformed into a deformed structure,greatly improve the processing performance of metal.
Another difference between cold rolling and hot rolling is the use. The cold rolling method is mostly used for molds, while the hot rolling method is more suitable for stamping and drawing. The same material has different physical properties due to different production processes. Aluminum processing, also known as plastic forming, is divided into casting, forging, extrusion, spinning, drawing, rolling, forming and other processing methods according to the force and deformation mode of aluminum during the deformation process.
The above is a brief introduction to the two production methods of cold-rolled and hot-rolled coated aluminum coils, I hope it can be of some help to you. kk Aluminum is a professional manufacturer of aluminum products, including aluminum skin, aluminum plate, etc. The quality is guaranteed and the price is very reasonable.
