Application:

Transportation:

It can be used to make all-aluminum trailers, aluminum alloy open-top coal cars, and high-precision aluminum alloy plates for automobiles, etc., which can effectively reduce vehicle weight, increase payload, and prolong service life. It is of great significance for energy conservation, emission reduction, and transportation efficiency.

Building Structure:

Aluminum Alloy Building Formwork:

The continuous improvement of the requirements of large construction enterprises for building standardization, industrialization and factory, as well as the improvement of the public’s requirements for housing quality, has promoted its application.

Aluminum Alloy Siding Sheet:

It is widely used in large infrastructure projects such as roofs and walls of public buildings such as airport terminals, convention centers, gymnasiums, etc., especially projects with large spans and complex appearance.

Power Field:

Copper resources in our country are relatively scarce and need to be imported in large quantities, while copper consumption accounts for a high proportion in the power field. To a certain extent, the use of aluminum alloy can reduce the external dependence on copper resources and enhance the ability to guarantee resources.

Computer field:

Utilizing the heat dissipation characteristics of aluminum alloy and the advantages of simple surface treatment, it can be applied to hardware such as main board radiators, cpu radiators, all-aluminum chassis and aluminum alloy keyboards.

Aerospace and military:

For example, it is used for aircraft parts, satellites, etc.

Daily necessities:

including lighting, solar reflectors; ceiling, wall, etc. of interior decoration; furniture, cabinets; elevators; signs, nameplates, luggage; interior and exterior decoration of automobiles; household appliances such as refrigerators, microwave ovens, audio equipment, etc.

Industrial equipment:

used for machining of mechanical parts, mold manufacturing, chemical/thermal insulation pipe coating, etc.

Physical and chemical properties:

Physical properties:

1. Small density: about 2.7g/cm ³, belonging to light metal material. 2. Good electrical and thermal conductivity: It has high electrical and thermal conductivity in metal. 3. Good ductility: It is easy to process into various shapes and thicknesses of plates, foils, etc. 4. Moderate strength: After alloying and heat treatment, its strength can be improved. 5. Surface gloss: It has good metallic luster.

Chemical properties:

1. Corrosion resistance: A dense oxide film can be formed in the air, making it resistant to corrosion to a certain extent. But in corrosive environments such as strong acids and alkalis, the oxide film may be destroyed. 2. Reactivity: Aluminum is a more active metal that can chemically react with oxygen, acid, alkali, etc. under certain conditions. 3. Reaction with oxygen: At room temperature, a thin and dense aluminum oxide protective film will form on the surface of aluminum to prevent further oxidation of internal aluminum. But under ignition or heating conditions, aluminum can react violently with oxygen to form aluminum oxide. 4. Reaction with acid: It can react with non-oxidizing acids such as dilute hydrochloric acid and dilute sulfuric acid to generate hydrogen and corresponding aluminum salts. 5. Reaction with alkali: It can react with strong alkali solutions such as sodium hydroxide to generate metaaluminate and hydrogen.
