In the aluminum sheet industry, there are many different types of 4 x 8 aluminum sheet, which can be divided into many models in different ways. When classified according to different production processes, aluminum sheet alloys can be divided into cold-rolled aluminum sheets and hot-rolled aluminum sheets. What is the difference between them? Let's find out together!
The difference between cold-rolled aluminum sheet and hot-rolled aluminum sheet is as follows:
First, the production process is different. The production process of cold rolled aluminum sheet starts with a cast slab (8 mm thick) made by a casting machine, which is then rolled by a cold rolling mill. Hot rolled aluminum sheets are made by heating aluminum ingots (400-500 mm thick) and then rolling them at high temperatures with a hot rolling mill.
Second, the supply of different raw materials. Hot rolled billets are aluminum ingots cast by heating and rolling, and cold rolled billets are cast rolls used for cold rolling.
Third, the performance is different. Hot rolled aluminum sheet has good surface quality, oxidation effect, bending properties, and strong mechanical properties and ductility. Cold-rolled aluminum sheets have poor mechanical properties and high hardness, so cold-rolled White Aluminum Sheet are often used as mold materials, and hot-rolled aluminum sheets are more suitable for deep drawing.
Generally speaking, the internal structure of hot-rolled aluminum sheet is stable and uniform, the hot-rolling process is complicated, and the price is higher than that of cold-rolling. At present, the 1 and 3 series aluminum sheets on the market are cold rolled, and the other series are hot rolled, but the 1 and 3 series can also be produced by hot rolling, but the price is higher.
