铝卷的密度因其材质和合金成分的不同而有所差异，常见的密度有以下几种：

The density of aluminum coils varies depending on their material and alloy composition. Common densities include the following:

　　1. 纯铝板：密度为2.71g/cm，该系列铝卷的铝含量都超过99%以上，其中还含有锰、硅等合金，所以密度稍微高于铝的密度。

1. Pure aluminum plate: The density is 2.71g/cm, and the aluminum content of this series of aluminum coils exceeds 99%. It also contains alloys such as manganese and silicon, so the density is slightly higher than that of aluminum.

　　2. 2系铝卷：代表产品是2024，密度为2.78g/cm，该系列铝卷的铜合金含量高，所以密度也比较大。

2.2 Series aluminum coils: The representative product is 2024, with a density of 2.78g/cm. This series of aluminum coils has a high copper alloy content, so the density is also relatively high.

　　3. 3系铝卷：密度为2.73g/cm，该系列铝卷内部含有锰合金。

3. Series 3 aluminum coils: with a density of 2.73g/cm, this series of aluminum coils contains manganese alloy inside.

　　4. 5系铝卷：密度为2.68g/cm，该系列铝卷内部镁合金含量高，而镁合金的密度要低于铝的密度。

4. 5 series aluminum coils: with a density of 2.68g/cm, this series of aluminum coils has a high content of magnesium alloy inside, and the density of magnesium alloy is lower than that of aluminum.

　　5. 6系铝卷：密度基本上在2.7g/cm附近，该系列铝卷内部含有镁合金和硅合金。

5-6 series aluminum coils: The density is basically around 2.7g/cm, and this series of aluminum coils contains magnesium alloy and silicon alloy inside.

　　总的来说，铝卷的密度一般在2.68g/cm-2.78g/cm之间。

Overall, the density of aluminum coils is generally between 2.68g/cm-2.78g/cm.
