Haomei Aluminum

  In the field of aluminum processing, hot rolling and cold rolling are two common production processes, each of which has unique features and advantages and is suitable for different application scenarios. In this article, we will make a comprehensive comparison between cold rolled and hot rolled aluminum sheets  in terms of production methods, alloys, thickness, width, quality and scope of use. – Comparison of production methods: The production of hot rolled aluminum sheet begins with casting aluminum ingots, which are heated to a high temperature and then rolled in a hot rolling mill. This process takes full advantage of the excellent plasticity of aluminum at high temperatures, enabling large processing rates and high productivity. In contrast, the production of cold rolled aluminum sheet is the molten aluminum directly cast into a certain thickness of the cast rolled coil, and then cold rolled and processed. The casting and rolling process is relatively simple...
