The difference between hot-rolled aluminum sheet and cast-rolled aluminum sheet
1. Different production processes: Casting and rolling is processed by a casting machine into a cast-rolled coil (8mm thickness) and processed by a cold rolling machine, while hot rolling is heated by an aluminum ingot (400-500mm thickness), which is heated by a high temperature. Rolled by hot rolling mill;
2. The supply of raw materials is different: the difference between the two is the supply of billets. The hot-rolled billet is cast aluminum ingot—heated—rolled into a coil for cold rolling, while the cast-rolled billet is cast-rolled coil—cast-rolled and rolled;
3. Different performance: hot-rolled
aluminum plate has good surface quality, strong mechanical properties and ductility, and good oxidation effect. At the same time, the processed aluminum disc is generally processed from aluminum plate, which is naturally also affected by the performance of aluminum plate;
4. Different uses: cast-rolled
aluminum sheets are mostly used in molds, and hot-rolled aluminum sheets are suitable for stamping and stretching.
5. Different prices: The process of cast-rolled
aluminum sheet is simple, and the price is cheaper than that of hot-rolled aluminum sheet.
6. Different finished products: Generally, the elongation of cast-rolled products is lower than that of hot-rolled products.
