Common alloys of mirror aluminum plates
Mirror aluminum plates are aluminum products with high reflectivity and flatness after special surface treatment (such as polishing, rolling, etc.). They are widely used in decoration, lighting, electronics and other fields. The commonly used aluminum alloys for manufacturing mirror aluminum plates are mainly the following:
1000 series pure aluminum:
This type of alloy is mainly composed of aluminum and contains very small amounts of other elements. It is characterized by good formability and corrosion resistance, but low strength. For example, 1050, 1060, 1070, etc.
3000 series aluminum-manganese alloy:
This series of alloys improves the strength and corrosion resistance of the material by adding manganese while maintaining good formability. Common ones include 3003, 3004, 3105, etc.
5000 series aluminum-magnesium alloy:
The mechanical properties and corrosion resistance of the alloy are improved by adding magnesium, especially the tensile strength of the material. This type of alloy has good welding performance and is suitable for applications requiring high strength. Common ones include 5052, 5083, etc.
6000 series aluminum silicon magnesium alloy:
This series of alloys further improves the strength of the material by adding silicon and magnesium, and can be strengthened by heat treatment. Common ones include 6061, 6063, etc.
Which alloy to choose as the raw material of mirror aluminum plate depends on the specific requirements of the final product, such as the demand for corrosion resistance, mechanical properties and cost considerations. In practical applications, it is also necessary to make appropriate choices according to different processing technologies.
