The aluminium sheet representing 2A16 (LY16) 2A06 (LY6) 2000 series is characterized by highhardness, in which the content of copper is the highest, about 3-5%. 3000 Series:Aluminum-manganese alloys
Represents 3003 30033A21 mainly. It can also be called rust-proof aluminium sheet. 3000 series aluminium sheet is mainly composed of manganese. The manganese content ranges from 1.0% to 1.5%. It is a series with better rust-proof function.
4000 Series:Al-Si alloys
The aluminium sheet representing the 4A01 4000 series belongs to the series with high silicon content. Usually the silicon content is between 4.5 and 6.0%. It belongs to building materials, mechanical parts, forging materials, welding materials, low melting point, good corrosion resistance.
5000 Series:Al-Mg alloys
Represents 5052.5005.5083.5A05 series. 5000 series aluminium sheet belongs to the more commonly used alloy aluminium sheet series,the main element is magnesium, the magnesium content is between 3-5%. It can also
be called Al-Mg alloy. The main characteristics are low density, high tensile strength and high elongation.
6000 Series:Aluminum Magnesium Silicon Alloys
The representative 6061 mainly contains magnesium and silicon, so it concentrates the advantages of 4000
series and 5000 Series. 6061 is a cold-treated aluminium forging product, which is suitable for applications requiring high
corrosion resistance and oxidation resistance.
7000 Series:Aluminum Zinc Alloys
The representative 7075 mainly contains Aluminum Zinc Alloys, Corrosion resistance: corrosion resistance includes chemical corrosion, stress corrosion and other properties.In general, the corrosion resistance of series 1 is the best, with series 5 performing well, followed by series 3 and 6, and series 2 and 7 performing poorly.The selection principle of corrosion resistance should be determined according to the application.All kinds of anticorrosive composite materials must be used in corrosive environment of high strength alloy
