Welcome to the official website of Jinan Kangzheng Aluminum Co., Ltd.!
Aluminum coil is a metallic sheet produced primarily from aluminum through casting‑rolling and rolling processes. As an industrial metal product, it finds extensive applications in construction, electronics, packaging, machinery, and transportation. Its manufacturing process complies with technical standards such as ISO 9001 and GB/T 3880‑2006, employing methods like direct casting of aluminum ingots followed by continuous casting and rolling. The product is widely used across sectors including construction, electronics, packaging, machinery, transportation, as well as emerging fields such as new energy, electrical engineering, and rail transit.
Based on alloying elements, aluminum coils are classified into series 1 through 9. Series 1 alloys (e.g., 1050) offer high purity at low cost; series 3, containing manganese, are suitable for humid environments; series 5 aluminum‑magnesium alloys are employed in aircraft fuel tanks; and series 7, rich in zinc, provides exceptional hardness and is commonly used for aircraft structural components. During machining, tool material should be selected according to silicon content; high‑silicon aluminum alloys typically require diamond tools. Coil thickness ranges from 0.2 mm to 10 mm, with thin sheets of 0.8–1.2 mm frequently used in construction and 0.6 mm specifications preferred for pipe insulation. Surface‑treatment technologies, including anodizing and color coating, meet both decorative and corrosion‑resistance requirements.
