What are the materials of aluminum coils?
1 series aluminum coil material
Series 1 aluminum coil is a common aluminum coil product among the 1000 series and has a relatively high aluminum content. They are all commonly used in our current lives! Especially because the aluminum content of 1 series aluminum coils is relatively high. For example, the aluminum content of 1060 aluminum coils reaches more than 99.6, has low density, is relatively soft, and is suitable for use in a variety of scenarios.
1 series representative materials: 1060 aluminum coil, 1050 aluminum coil, 1100 aluminum coil, 1050A aluminum coil material
1060 aluminum coil alloy composition: iron (Fe) 0.35%, manganese (Mn) 0.03%, magnesium (Mg) 0.03%, silicon (Si) 0.25%, zinc (Zn) 0.05%, titanium (Ti) 0.03%, copper ( Cu)0.05%, aluminum (Al) exceeds 99.6%.
1100 aluminum coil composition:
Aluminum Al: 99.00, silicon Si: 0.45, copper Cu: 0.05 ~ 0.20, magnesium Mg: --, zinc Zn: 0.01, manganese Mn: 0.035, titanium Ti: --, vanadium V: 0.05, iron Fe: 0.35.
2 series aluminum coil material
Series 2 aluminum coils are an aluminum plate and strip product with a high copper content. Some aluminum coil materials contain copper content as high as 3% to 5%. At the same time, the hardness of the 2 series material is relatively high, and it is often called a special product for aviation aluminum. However, there are currently relatively few manufacturers that can produce 2 series aluminum coil products.
2 series representative materials: 2A16 aluminum coil, LY16 material, 2A12 aluminum coil, 2A21 aluminum coil material
2A21 aluminum coil alloy composition:
Magnesium Mg: 1.2～1.8, zinc Zn: ≤0.30, manganese Mn: 0.30～0.9, titanium Ti: ≤0.15, nickel Ni: ≤0.10, iron Fe: 0.000～ 0.500, iron nickel Fe Ni: 0.000～ 0.50.
3 series aluminum coil material
For 3XXX series aluminum coils, they are actually relatively common products, especially the representative 3003 aluminum plate. Generally, the aluminum content of 3 series aluminum coils is 99.8%, and the manganese content is between 1% and 1.5%. Series 3 aluminum coils are also often called aluminum-manganese alloy aluminum coils. Because their alloy content contains a relatively large proportion of manganese, they are also called rust-proof aluminum sheets.
3 series representative materials: 3003 aluminum coil, 3A21 aluminum coil, 3004 aluminum coil, 3005 aluminum coil material
3003 aluminum coil alloy composition:
Silicon Si: 0.6, copper Cu: 0.05--0.2, zinc Zn: 0.1, manganese Mn: 1.0--1., iron Fe: 0.7, alone: 0.05, aluminum, balance.
