In the procurement process of
aluminum discs, for different needs on the type of aluminum round, grade, process have different requirements, especially the cold-rolled aluminum rounds and hot-rolled aluminum rounds of the distinction, identification, has a pivotal role. The differences between Cold-rolled aluminum sheet and hot-rolled aluminum sheet are as follows:
1. Different production process: Cold rolled
aluminum disc is produced by cold rolling machine from the aluminum coil (8mm thickness), while hot-rolled is made by heating aluminum slab (400-500mm thickness) and rolling it at high temperature by a hot rolling mill.
2. Different Raw materials: the difference between them in the aluminum billet supply is not the same. The hot-rolled billet is cast aluminum ingot – heating – rolled into a coil for cold rolling, the cold-rolled billet is cast roll – cold rolling.
3. Different performance: Hot-Rolled aluminum disc surface quality, while mechanical properties and ductility, oxidation effect is good, while processing aluminum discs are generally processed from the aluminum plate, naturally also affected by the performance of the aluminum plate.
4. Different applications: CC aluminum discs are mostly used in the production process of spinning; DC aluminum discs suitable for stamping and deep drawing production process.
Through the above four methods, you can easily distinguish between cold-rolled aluminum discs and hot-rolled aluminum discs. The choice of aluminum discs requires professional knowledge, aluminum discs procurement more need to choose a professional manufacturer.
