aluminum coil, to put it more colloquially, refers to the roll shape of aluminum material, which is a classification of aluminum plates, also known as aluminum coil plates. aluminum coil is made of aluminum raw material that is rolled by a rolling mill, then trimmed and annealed. aluminum coils are divided into hot-rolled coils and cold-rolled coils due to different processing techniques. aluminum coils are made of different materials, roughly divided into pure aluminum coils and alloy aluminum coils. aluminum coils are widely used, and continuous punching molds use aluminum coils for high efficiency and cost savings for customers. aluminum coils are often seen in fields such as electronic product processing, mechanical parts manufacturing, pipeline insulation engineering, and so on.
