Aluminum wine label

Why choose aluminum as the material for wine labels?

The advantages and characteristics of aluminum are as follows:

1. Low density. The density of aluminum is about 2.7g/cm3. Its density is only 1/3 of that of iron or copper.

2. High plasticity. Aluminum has good ductility and can be made into various products through pressure processing methods such as extrusion and stretching.

3. Corrosion resistance. Aluminum is a highly negatively charged metal. A protective oxide film will be formed on the surface under natural conditions or anodic oxidation, which has much better corrosion resistance than steel.

4. Easy to strengthen. The strength of pure aluminum is not high, but its strength can be improved after anodizing.

5. Easy surface treatment. Surface treatment can further improve or change the surface properties of aluminum. The aluminum anodizing process is quite mature and stable in operation, and has been widely used in the processing of aluminum products.

6. Good electrical conductivity and easy to recycle.
