1000 Series:Industrial Pure Aluminum
Represents the 1000 series of aluminium sheets, also known as pure aluminium sheets, in all series, 1000 series belongs to the series with the largest aluminium content. The purity can reach over 99.00%.
2000 Series:Aluminum-copper alloys
The aluminium sheet representing 2A16 (LY16) 2A06 (LY6) 2000 series is characterized by high hardness, in which the content of copper is the highest, about 3-5%.
3000 Series:Aluminum-manganese alloys
Represents 3003 3003 3A21 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
