In the process of <strong>
aluminum alloy plate processing</strong>, various elements are added to achieve some special mechanical properties of
aluminium sheet.<br><br>
Aluminum alloy sheets can be divided into 1-8 series
aluminum sheet . For example, 2A21 aluminum belongs to 2 series 3003 aluminum belongs to 3 series, 5052 aluminum belongs to 5 series, and so on.<br><strong>Food grade
aluminum plate</strong> production and processing methods belong to rolling processing, also known as "calendering" processing. Generally, there are two ways: hot rolling and casting rolling.<br>
Characteristic of hot rolling process for
aluminium sheet: In the process of large plastic deformation, internal structure undergoes many times of recovery and recrystallization, crushing coarse grains in casting state and healing micro-cracks, resulting in remarkable improvement of casting defects such as homogenization of internal structure, size and shape of grains, change of point defects and concentration of line defects, and transformation of as-cast structure into deformation. The structure greatly improves the processing performance of metals. Especially in deep drawing performance, hot rolled materials have incomparable advantages over Cast-rolled materials.<br>
Characteristic of casting-rolling method: The internal structure of cast-rolling
aluminium plate belongs to semi-cast structure, and the orientation of crystal is strong. Compared with hot rolling, it has the characteristics of less investment, low cost and high efficiency.<br>
Alloy
aluminium sheet can also be divided into <strong>cold rolled
aluminum sheet</strong> and hot rolled
aluminum sheet, the main difference is the difference between anodic oxidation, hot rolled
aluminium sheet can be used as anodic oxidation. Cold rolled
aluminium sheet and hot rolled
aluminium sheet have different uses. Cold rolled
aluminium sheet is mostly used for dies and hot rolled
aluminium sheet is suitable for stamping and drawing. The physical properties of the same material of
aluminium coil vary greatly due to different manufacturing processes. Aluminum processing is also known as plastic forming. According to the stress-strain state of aluminum during deformation, it can be divided into casting, forging, extrusion, spinning, drawing, rolling, forming (cold pressing, deep drawing) and other processing methods.</p>
