cold rolled aluminum and hot rolled aluminum
In the process of aluminum plate procurement, different requirements have different requirements on the type, material and process of aluminum plate, especially the distinction and recognition between cold rolled aluminum plate and hot rolled aluminum plate, which plays an important role. Aluminum plate industry, aluminum plate classification, according to the production process, aluminum plate can be divided into cold rolled aluminum plate and hot rolled aluminum plate. The difference between cold rolled aluminum sheet and hot rolled aluminum sheet is as follows:

Method 1: the production process is different: the cold rolling is made by casting and tying machine (8mm thickness), which is processed by cold rolling machine. The hot rolling is made by heating aluminum ingots (400-500mm thickness), which is rolled by hot rolling mill at high temperature.
Method 2: the supply of raw materials is different: the two are different in the supply of blank. The hot-rolled blank is cast aluminum ingots — heated — rolled into rolls for cold rolling.
Method 3: different properties: hot rolled aluminum plates have good surface quality, strong mechanical properties and ductility, and good oxidation effect. Aluminum wafers processed at the same time are generally processed by aluminum plates, and naturally affected by the performance of aluminum plates.
Method 4: different USES: cold rolled aluminum plate is mainly used in the mold, hot rolled aluminum plate is suitable for stamping and stretching aspects.
Through the above four methods, we can easily distinguish the cold rolled aluminum sheet from hot rolled aluminum sheet. The choice of aluminum sheet requires professional knowledge, and the purchase of aluminum sheet requires more professional manufacturers.
