5252 Aluminium Sheet products The difference between cold rolling and hot rolling
08-22
1. Appearance difference
The surface difference between cold-rolled and hot-rolled 5252 Aluminium Sheet products can be seen from the appearance alone that the surface of the hot-rolled aluminum sheet will be a little gray and black, and the brightness may not be as much as that of the cold-rolled aluminum sheet.
The reason for this is that hot-rolled aluminum sheets are often made of alloys, especially manganese, magnesium, silicon and other metals will cause the surface of the aluminum sheet to be gray and black, so the surface of the two will be gray and cold compared to the hot-rolled sheet. Rolling will not.
Usually, the surface brightness of the hot-rolled sheet is better than that of the cold-rolled sheet, but this should also be compared with the thickness of the aluminum sheet.
2. Performance difference
5252 Aluminium Sheet products The difference between cold rolling and hot rolling is obvious. The mechanical properties of hot rolled sheets and the ductility of aluminum sheets are better.
Especially the oxidation process of hot-rolled aluminum plate, the effect is extremely good, compared with cold aluminum plate and aluminum coil, the oxidation effect of hot-rolled aluminum plate must be better.
The process of hot rolling 5252 Aluminium Sheet products is to use vertical casting into billets, which is what we call large slabs, and finally roll them into coils by heat treatment.
