First, the performance characteristics of aluminum
1. light weight and high strength: the density of aluminum is about 2.7g/cm³, about 1/3 lighter than steel, but the strength is comparable to steel, the use of aluminum can reduce the weight of the entire structure, improve the carrying capacity.
2. good corrosion resistance: the surface of the aluminum plate is easy to form a layer of dense oxide film, which can effectively resist the corrosion of the external environment, such as oxygen, water, but also to protect the aluminum itself.
3. good electrical and thermal conductivity: aluminum is a good electrical and thermal conductivity of the material, its electrical conductivity than copper is a little worse, but the thermal conductivity is superior to copper, and has a lower temperature coefficient.
4. Easy to process and form: aluminum plate is easy to process into various shapes and sizes of parts, which can be achieved by shearing, stamping, rolling, stretching and other processing techniques.
Second, the application of aluminum plate
1. automobile manufacturing: aluminum plate's light weight, high strength and good corrosion resistance, especially for automobile manufacturing body, engine and parts and other fields.
2. electronic appliances: aluminum sheet of good thermal conductivity, making it suitable for the manufacture of a variety of radiators, fume hoods, electrolytic capacitors and other electronic and electrical products in the field.
3. air-conditioning equipment: aluminum plate's light weight and high strength and good thermal conductivity, so that it has a wide range of applications in the field of air-conditioning equipment.
4. building decoration: aluminum plate's color variety, light weight, good flexibility and other characteristics, so that it is widely used in the field of building decoration, such as aluminum curtain walls, ceilings, doors and windows.
5. Packaging materials: aluminum can be made into a variety of packaging materials, such as easy-to-open lids, can lids, food bags, etc., with good sealing and preservation of freshness.
In summary, aluminum plate has excellent performance characteristics and a wide range of applications. As an environmentally friendly and energy-saving new material, aluminum sheet has a very broad development prospect in the future.
