Hot rolled aluminum coil is a kind of aluminum material that has been heated and pressure treated, by heating the aluminum blank to the appropriate temperature, and then processed into rolled products by rolling machines. Hot-rolled aluminum coils are commonly used in industries such as construction, aerospace, automotive, home appliances, and packaging.

　　First, after the aluminum billet is melted and cast, it is heated to the appropriate temperature, usually rolling at a relatively high temperature, so that the aluminum billet becomes softer and easier to process. Then, after the processing of the rolling machine, the aluminum billet is rolled into a thin and wide rolled product, which is hot rolled aluminum coil.

　　Hot rolled aluminum coil has many advantages. First of all, it has excellent mechanical properties, with high tensile strength and compressive strength, so it is very popular in a wide range of industrial applications. Secondly, hot rolled aluminum coil has good corrosion resistance, has good oxidation resistance and corrosion resistance, so it can be used for a long time in humid, acidic or alkaline environments, and is very suitable for outdoor use. In addition, the hot-rolled aluminum coil also has good weldability and processing performance, and can be easily welded, bent, cut, forming and other processing operations, so it is very convenient to process into various models and sizes of parts.

　　In addition to the above advantages, hot rolled aluminum coil also has a good surface texture and appearance, through different surface treatment processes to create bright, matte, matte or textured surface effects, in line with the appearance requirements of different applications. In addition, the hot-rolled aluminum coil also has a high recycling rate, which can reduce the consumption of raw materials through recycling and recycling, which is conducive to environmental protection and sustainable development.

　　In general, hot rolled aluminum coil is a very commonly used and important aluminum material products, with good mechanical properties, corrosion resistance, processability and recyclability, widely used in construction, aerospace, automotive, home appliances and packaging industries, to meet the needs of different industries for aluminum materials. With the continuous progress of technology, the performance and quality of hot-rolled aluminum coil will continue to improve, providing more high-quality material support for the development of various industries.
