Aluminum coils come in a variety of specifications and thicknesses

Aluminum coils come in a variety of specifications and thicknesses to meet the needs of different industries and applications. Common aluminum coils range in thickness from 0.05mm to 15mm, and widths from 15mm to 2000mm. For example, aluminum coils for thermal insulation are usually 0.3mm to 0.9mm thick and 500mm to 1000mm wide. In addition, the length of aluminum coils is usually unlimited, which provides great flexibility for large projects.

The specifications of aluminum coils vary in different series. The 1000 series, also known as pure aluminum coils, usually contain more than 99% aluminum, have a simple production process, and are relatively cheap, and are widely used in industry. The 2000 series uses copper as the main alloying element, has a high hardness, and is mainly used in the aerospace field. The 3000 series contains manganese, has good rust resistance, and is often used in humid environments. The 4000 series contains a high silicon content and is suitable for building materials and mechanical parts. The 5000 series, with magnesium as the main element, has low density and high strength, and is suitable for aviation and marine fields. The 6000 series contains magnesium and silicon, has good usability and corrosion resistance, and is suitable for various industrial structural parts. The 7000 series contains zinc elements and is a high-strength alloy, which is often used in high-stress structural parts and mold manufacturing.

The thickness of aluminum coils is also classified according to different standards. According to the GB/T3880-2006 standard, aluminum materials with a thickness of less than 0.2mm are called aluminum foil, while materials with a thickness of more than 0.2mm to less than 500mm are called aluminum plates or sheets. The thickness of aluminum coils can also be subdivided into thin plates (0.15mm-2.0mm), regular plates (2.0mm-6.0mm), medium plates (6.0mm-25.0mm), thick plates (25mm-200mm) and extra-thick plates (more than 200mm).

When selecting aluminum coils, in addition to considering specifications and thickness, factors such as its alloy composition, mechanical properties and surface treatment need to be considered to ensure that the selected materials can meet the requirements of specific applications. For example, some aluminum coils require additional surface treatments, such as anodizing, coating or etching, to improve their corrosion resistance, wear resistance or decorative effects. In addition, the processing technology of aluminum coils, such as cold rolling or hot rolling, will also affect its final performance and application range. Therefore, understanding aluminum coils of different specifications and thicknesses and their characteristics is crucial to ensure product quality and project success.
