In the aluminium plate industry, there are many classifications of aluminium alloy plate. According to different production processes, aluminium plate can be divided into cold-rolled aluminium plate and hot-rolled aluminium plate. The differences between cold rolled and hot rolled aluminium sheets are as follows:
1. The production process is different: cold rolling is processed by casting machine into casting coil (8mm thickness aluminum brazing sheet plate ) and processed by cold rolling mill, while hot rolling is heated by aluminium ingot (400-500mm thickness aluminium) and rolled by hot rolling mill at high temperature.
2. Material supply is different: the difference between the two is that the billet supply is different. The hot-rolled billet is cast aluminium ingot-heating-rolling coil for cold rolling, and the cold-rolled billet is cast-rolling coil-cold rolling.
3. Different properties: hot-rolled aluminium sheet has good surface quality, strong mechanical properties and ductility, and good oxidation effect. At the same time, the processing of aluminium circles is generally processed from aluminium sheet, which is naturally affected by the properties of aluminium sheet.
4. Different uses: cold-rolled aluminium sheets are mostly used in die and hot-rolled aluminium sheets are suitable for stamping and drawing.
