Flat aluminum strips can be made from a variety of alloys to meet different performance and application needs. Common aluminum alloys include 1060, 3003, 5052 and others. These aluminum alloys have different mechanical properties, corrosion resistance and machinability, and are suitable for different industrial applications. For example, 3003 aluminum alloy aluminum strip has good formability, corrosion resistance, weldability, medium strength, and is used for aluminum products requiring a certain degree of strength and good processing performance, such as kitchenware, food and chemical product handling and storage devices, tanks and troughs for the transportation of liquid products, a variety of pressure vessels and piping processed in thin sheets, heat exchangers, rivets, welding wires, washing machine cylinders, and refrigerator liners.
The production process of flat aluminium strip mainly includes melting, casting, rolling, annealing and surface treatment steps:
- Melting: High purity aluminum ingot or aluminum alloy ingot is melted in a high temperature furnace, and appropriate amount of alloying elements are added to obtain the required chemical composition and properties.
- Casting: The melted aluminum liquid is passed through the casting machine into ingots. The quality of the ingot directly affects the subsequent rolling and annealing processes.
- Rolling: The ingot is rolled through a number of rolling processes, such as primary rolling, intermediate rolling and finishing rolling, to gradually thin and reach the required thickness and width. The rolling process requires strict control of rolling speed, rolling force and rolling temperature to ensure uniform thickness and smooth surface of the aluminum strip.
- Annealing: In order to remove the internal stresses generated during the rolling process and improve the plasticity and toughness of the aluminium strip, annealing treatment is required. The annealing process needs to be carried out at a specific temperature and time.
- Surface treatment: Finally, surface treatment, such as cleaning, polishing, coating, etc., is carried out to improve the appearance quality and corrosion resistance of aluminum strip.
Through the above production process, flat aluminum strips products with smooth surface and excellent performance can be produced.
Aluminum flat strip is available in a wide range of thicknesses to meet the needs of different fields and applications. The common thickness range varies from a very thin 0.08mm to a thicker 3.2mm, and even thicker aluminum strips are produced. Different thicknesses of aluminum strip are suitable for different application scenarios, such as thin aluminum strip is commonly used in the manufacturing of electronics, while thicker aluminum strip may be used for construction or mechanical structural components.
Aluminium flat strip with flat surface has a wide range of applications in several fields due to its excellent physical and chemical properties. The following are some of the major application areas:
- Construction: Used in architectural curtain walls, ceiling suspended ceilings, decorative materials (such as decorative panels, partitions, doors and windows), etc. It provides beautiful, durable, corrosion-resistant decorative and structural materials.
- Transportation Manufacturing: Used in the manufacturing of automobiles, trains, airplanes, and other means of transportation, utilizing its lightweight, corrosion-resistant, and easy-to-process features to reduce the weight of vehicles and improve fuel efficiency.
- Electronic products: Due to its conductivity and plasticity, aluminum strip is also widely used in the manufacture of electronic products, such as the encapsulation of electronic components and the production of heat sinks.
- Packaging industry: As a packaging material, it is used to protect goods from damages such as moisture and oxidation.
