Precautions for the purchase and use of aluminum p

  • Detail

With the rapid development of aluminum profile industry, domestic excellent aluminum profile production enterprises pay more and more attention to the research on the industry market, especially the in-depth research on the development environment of enterprises and the changes of customer demand trends. Because of this, a large number of domestic excellent aluminum profile brands have risen rapidly and gradually become the leaders in the aluminum profile industry! There are about 300 kinds of alloys and 1500 varieties of aluminum processing materials in China, which is one of the countries with the richest product varieties in the world

aluminum profile is the aluminum bar through different degrees of hot melting and extrusion, so that it can form aluminum materials with different shapes. Aluminum profile is also widely used, often used in construction, home decoration, industry and so on. Among many varieties of aluminum processing materials, a large number of international advanced products and national famous brand products have emerged, representing the mainstream direction of the development and application of modern aluminum processing technology in China. Next, let's learn about the relevant knowledge of aluminum profiles

classification of aluminum profiles

1 Architectural aluminum profiles

2. Radiator aluminum profile

3. Industrial aluminum profiles: used in industrial production and manufacturing, mostly used in electronic machinery industry and dust-free room

4. Aluminum profile of railway vehicle structure: used for the manufacturing of railway vehicle body

5. Mount Aluminum profiles and make them into aluminum alloy picture frames

aluminum profile features

corrosion resistance

density 2.7g/cm3, with excellent corrosion resistance


excellent conductivity, nearly twice that of copper

thermal conductivity

the thermal conductivity is 50-60% of that of copper, which is beneficial to the manufacture of radiators


specific tensile strength, yield strength, ductility


extremely high recoverability, there is no difference between recycled aluminum and primary aluminum

precautions for the purchase and use of aluminum profiles

1 Pay attention to the factory date, specification, technical conditions, enterprise name and production license number

2. The product has bright color, good gloss and no defects

3. The thickness of the product shall not be less than 1.0mm

4. The film thickness shall not be less than 10-mu; m. The coating thickness shall not exceed 40-120 mu; M range

5. Choose profile products with good corrosion resistance

6. Do not use hard objects as cleaning tools

7. It can be wiped with water, detergent and soap

poor quality characteristics of aluminum profile

extrusion defects. Whether the extrusion process is mature and the operation is proper

the thickness of oxide film is thin. Not less than 10um. Spot check the aluminum profiles with factory address, production license and certificate of conformity

unqualified chemical composition. Unqualified chemical composition seriously endangers the safety of construction projects

reduce the wall thickness of the profile. 90 series, the minimum wall thickness is not less than 1.4mm

editor's summary: the above is the introduction of relevant knowledge about the purchase and use precautions of aluminum profiles. I hope to help friends with this need!
