Application:

1. Construction field: used as a decorative material for building facade, such as aluminum curtain wall. – For example, the appearance of many modern office buildings uses a unique shape made of aluminum coil.

2. Transportation: used for body panels, engine covers, etc. in automobile manufacturing. – Some new energy vehicles use aluminum coil for body parts to reduce weight.

3. Home appliance industry: making the shell and internal parts of refrigerators and air conditioners. – Many shells of common household air conditioners and outdoor units are processed from aluminum coil.

4. Packaging industry: used for packaging materials for food, medicine, etc. – such as the manufacture of cans is inseparable from aluminum coil.

5. Electronic equipment: as the shell and heat dissipation parts of electronic products. – The shell of the laptop may be made of aluminum coil material, which helps to dissipate heat and reduce weight.

6. Solar energy field: used for the frame and support structure of solar panels. 7. Plumbing engineering: manufacturing ventilation ducts, etc.

Physical properties:

1. Density: about 2.70 g/cm ³, is a lightweight metal, easy to handle and process. – For example, in the manufacture of lightweight vehicles, it can effectively reduce its own weight.

2. Melting point: about 660 ° C, the melting point is relatively low. – This requires special attention to control the temperature in some processes that require thermal processing.

3. Thermal conductivity: Good thermal conductivity, is an excellent heat conduction material. – Often used in radiators and other components that require efficient heat dissipation.

4. Conductivity: second only to silver, copper and gold, with high electrical conductivity. – Often used in conductive components in power transmission lines and electronic equipment.

5. Ductility: It has excellent ductility and is easy to roll into a thin sheet.

Chemical properties:

1. Corrosion resistance: It is easy to form a dense alumina protective film in the air, which has certain corrosion resistance. – But in a strong acid and alkali environment, this protective film will be destroyed.

2. Reactivity: It is more active and can chemically react with acids and bases. – For example, it reacts with hydrochloric acid to form aluminum chloride and hydrogen.

3. Oxidation: It is easy to oxidize with oxygen at high temperatures.

4. Electrochemical properties: It is more active in electrochemical sequences and is prone to electrochemical corrosion.
