The difference between cold-rolled aluminum plate and hot rolled aluminum plate is as follow.
1.The production process
Casting machines process the aluminum into casting rolling coils (8mm in thickness).Then the casting rolling coils are processed by cold rolling machines. While,on hot rolling fabrication, aluminum plate ingots (400-500mm in thickness) have to receive heating treatment by hot rolling mill.
2.Raw materials
The billet for cold rolling is made of casting roll.While the billet for hot rolling billet is made of casting aluminum ingot.By heating and then rolling ,the aluminum billet becomes aluminum coil.
3.The performance
Hot-rolled aluminum plate’s surface quality is better than that of cold rolled aluminum plate.Meanwhile. Hot-rolled aluminum plate’s mechanical properties and ductility can be strong,and its oxidation effect is good .
4.Applications
Cold-rolled aluminum plate is mainly used for mold products,and hot-rolled aluminum plate is suitable for product that requires stamping elongating.
