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

1. Different production processes: Cold rolling is processed by a casting machine into a casting coil (8mm thickness) processed by a cold rolling mill, while hot rolling is an aluminum ingot (400-500mm thickness) heating, at high temperature Hot rolling mill rolling;

2. Different raw material supply: the difference between the two is different in the supply of the blank. The hot rolled billet is cast aluminum ingot--heating-rolling into a coil for cold rolling, and the cold-rolled billet is cast-rolling--cold rolling;

3. Different performance: The surface quality of hot-rolled aluminum sheet is good, and the mechanical properties and elongation properties are strong, and the oxidation effect is good. At the same time, the processing of aluminum discs is generally processed from aluminum sheets, and naturally it is also affected by the performance of aluminum sheets;

4. Different uses, cold-rolled aluminum sheets are mostly used in molds, and hot-rolled aluminum sheets are suitable for stamping and stretching.
