Aluminum coil is a kind of metal sheet, which is melted from aluminum ingots, plus different alloys, processed into aluminum coils by casting or hot rolling, cold rolling, annealing, and cross-cutting. Aluminum coils have low density, light weight, and easy handling. It can be strengthened, plasticity, good thermal conductivity. Therefore, it is widely used in power plants and chemical plants for pipe insulation, heat exchangers, evaporators, heating appliances, cooking utensils, etc.
Comparison of Chinese and foreign implementation standards for aluminum coils:
China: GB/T 3880-2006 /GB/T 28904-2012
American Standard: ASTM B209
Japanese standard: JIS H4000-2006
