Aluminum profile industry has become a very mature industry. The density of aluminum is very small, only 2.7g/cm. Although it is relatively soft, it can be made into various aluminum alloys, such as duralumin, super duralumin, antirust aluminum, cast aluminum, etc. Now the application of aluminum shell is very extensive, so what are the characteristics of aluminum shell products?

1. the aluminum shell is light in weight, good in steel and high in strength. The 3.0mm-thick aluminum single plate weighs 8kg per square plate and has a tensile strength of 100-280n2.

2. Aluminum shell has good weather resistance and corrosion resistance.

Third, it is not easy to stain, and has good self-cleaning. The non adhesion of fluorine coating film makes it difficult to attach pollutants on the surface.

4. The aluminum shell has various colors and large selection space.

5. aluminum shell has good technology. Because it adopts the process of processing before painting, and aluminum plate can be processed into various complex geometric shapes such as plane, arc and sphere.

The main alloy elements of aluminum alloy shell are magnesium and silicon, which have excellent processing performance, excellent weldability, extrudability and electroplating, good corrosion resistance and toughness, easy to polish and color film, and excellent anodizing effect. It is a typical extrusion alloy. How can we distinguish the quality of aluminum shell?

1. the surface characters of aluminum shell materials are generally printed by imported ink jet printing, and the handwriting is clear, and the general marks such as trademark identification, manufacturer, address and even telephone are clear and true; the surface characters of fake and inferior aluminum veneer materials are mostly printed by ordinary printing machine, and the handwriting is pasted, and the manufacturer and logo are generally unknown or not marked.

2. The aluminum shell material is made of high-quality raw materials, with high process accuracy, smooth and smooth feel on the surface and inner layer, and flat without speckles;

3. The wall thickness of the aluminum shell is uniform, the combination of the aluminum veneer materials is tight, and the quality and thickness of the aluminum plate can meet the national standard; the wall thickness deviation of the fake and inferior products is large, the aluminum plate is thin, and the gap between the lap joints of the aluminum veneer materials is large.

4. High quality aluminum shell can use small pressure pump to test the pressure resistance of aluminum sheet material. The internal pressure of the real aluminum veneer is high, which can generally meet or exceed the requirements of the relevant national specifications; while the internal pressure of the fake and inferior products is generally low, which is difficult to meet the use requirements.
