In the process of purchasing aluminum sheets, according to different requirements, there are different requirements for the types, grades and processes of aluminum sheets, especially the distinction and identification of 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. The production process is different: the cold-rolled aluminum plate is produced by the aluminum coil (8mm thick) through the cold rolling mill, while the hot-rolled aluminum plate (400-500mm thick) is heated and rolled by the hot rolling mill at high temperature. mill.
2. Different raw materials: Their differences in the supply of aluminum ingots are different. Hot-rolled slabs are cast-heated-rolled aluminum ingots for cold rolling, and cold-rolled slabs are cast-rolled-cold-rolled.
3. Different properties: hot-rolled aluminum sheet has good surface quality, good mechanical properties, ductility, and oxidation effects, while processed aluminum sheets are generally aluminum sheets, which are naturally affected by the properties of aluminum sheets.
4. Different uses: CC aluminum plate is mostly used in spinning process; DC aluminum plate is suitable for stamping and deep drawing production process.
