Common aluminum coil alloy composition and use

With the increase in the use of aluminum coils and the application advantages of aluminum gradually becoming prominent, more and more customers can choose suitable aluminum coils for use as products, so what are the materials of aluminum coils?


1. What is the material of the aluminum coil?

(1) 1 series aluminum coil material

The 1-series aluminum coil belongs to the 1000 series, which is relatively common, and = an aluminum coil product with a relatively high aluminum content. They are all commonly used in our current life! Especially because the aluminum content of the 1 series aluminum coil is relatively high. For example, the aluminum content of the 1060 aluminum coil reaches more than 99.6, the density is small, and it is relatively soft, which is suitable for use in a variety of scenarios.

1 series representative material: 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) more than 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) 2 series aluminum coil material

The 2-series aluminum coil belongs to an aluminum sheet and strip product with a high copper content. Some aluminum coils contain copper content as high as 3% to 5%. At the same time, the hardness of the 2 series of materials is relatively high, and it is usually called as a special product for aviation aluminum, but there are relatively few manufacturers that can produce the 2 series of 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 FeNi: 0.000~0.50.

(3) 3 series aluminum coil material

For the 3XXX series aluminum coil, it is actually a relatively common product, especially the representative 3003 aluminum plate. Under normal circumstances, the aluminum content of the 3 series aluminum coil is 99.8%, and the manganese content is between 1% and 1.5%. 3-series aluminum coils are also commonly referred to as aluminum-manganese alloy aluminum coils. Due to the large proportion of manganese in their alloy content, they are also called rust-proof aluminum sheets.

3 series representative material: 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.

(4) 5 series aluminum coil material

The 5 series aluminum coil is another commonly used aluminum coil material after the 1 series and 3 series. The representative alloy elements of the 5 series are mainly aluminum, magnesium and manganese alloys. Therefore, the aluminum-magnesium-manganese sheet mentioned by many friends is also the 5-series aluminum coil, because the 5-series aluminum coil has aluminum-magnesium-manganese elements, so it has a wide range of uses and excellent performance. Aluminum sheets are widely used.

5 series representative material: 5052 aluminum coil, 5A21 aluminum coil, 5005 aluminum coil, 5083 aluminum coil material.


5052 aluminum coil alloy composition:

Aluminum Al: balance, silicon Si: ≤0.25, copper Cu: ≤0.10, magnesium Mg: 2.2~2.8, zinc Zn: ≤0.10, manganese Mn: ≤0.10, chromium Cr: 0.15~0.35, iron Fe: ≤0.40, Note: Single: ≤0.05; Total: ≤0.15.

(5) 6 series aluminum coil material

Magnesium and silicon are the core representative elements of the 6-series aluminum coil as a whole. The material of the 6-series aluminum coil is a cold-treated aluminum forging product, so it is also called an aluminum-magnesium-silicon product. It has excellent performance and good oxidation effect, so it is more suitable for various environments.

6 series representative material: 6061 aluminum coil, 6063 aluminum coil, 6082 aluminum coil material.


6061 aluminum coil alloy composition:

Silicon Si: 0.40-0.8, Iron Fe: 0.7, Copper Cu: 0.15-0.40, Manganese Mn: 0.15, Magnesium Mg: 0.8-1.2, Chromium Cr: 0.04-0.35, Zinc Zn: 0.25, Titanium Ti: 0.15, Aluminum Al : Margin, Others: Single: 0.05 Total: 0.15.

(6) 7 series aluminum coil material

The main alloying elements of the 7 series are still mainly zinc, followed by the sum of three aluminum-magnesium-new-copper alloys, which can be hot-processed and belong to the superhard aluminum alloy series. It has good wear resistance and will not cause great deformation after thermal processing, so it is very popular among customers.

7 series representative material: 7075 aluminum coil, 7011 aluminum coil, 7072 aluminum coil material.


7075 aluminum coil alloy composition:

Silicon Si: 0.40, Iron Fe: 0.50, Copper Cu: 1.2-2.0, Manganese Mn: 0.30, Magnesium Mg: 2.1-2.9, Chromium Cr: 0.18-0.28, Zinc Zn: 5.1-6.1, Titanium Ti: 0.20, Aluminum Al : Margin, Single: 0.05, Total: 0.15.

(7) 8 series aluminum coil material

The main uses of 8 series aluminum coils are concentrated in wafers, kitchen utensils, bottle caps, etc. The frequency of use is relatively large. The most widely used are aluminum foil processing, wafer processing, etc., which are all well-applied and used products.

2. What are the uses of aluminum coils?


Aluminum coil products are widely used in aerospace, molds, instrumentation, construction, packaging, air conditioners, cables, automotive cooling, medicine, solar energy, cosmetics, etc. It can also be used in power plants, chemical plants, petrochemical plants, etc. to meet the different needs of users.
