In the aluminum plate industry, there are many classifications of aluminum plates. According to different production processes, aluminum plates can be divided into cold-rolled aluminum plates and hot-rolled aluminum plates. The difference between cold rolled aluminum sheet and hot rolled aluminum sheet is as follows:

1.The production process is different: cold rolling is processed by a casting machine into cast rolls (8mm thickness) and processed by a cold rolling machine, while hot rolling is heated by an aluminum ingot (400-500mm thickness), which is heated at high temperatures. Rolled by hot rolling mill;

2.The supply of raw materials is different: the difference between the two is that the supply of billets is different. The hot-rolled billet is cast aluminum ingot-heated-rolled into coils for cold rolling, and cold-rolled billet is cast-rolled coil-cold-rolled rolling;

3.Different properties: The hot-rolled aluminum sheet has good surface quality, strong mechanical properties and ductility, and good oxidation effect. At the same time, the processed aluminum wafers are generally processed from aluminum plates, which are naturally affected by the properties of aluminum plates;

4.Different uses: cold-rolled aluminum plates are mostly used in molds, and hot-rolled aluminum plates are suitable for stamping and drawing.
