鋁卷的密度因其材質和合金成分的不同而有所差異，常見的密度有以下幾種：

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

　　1. 純鋁板：密度為2.71g/cm，該系列鋁卷的鋁含量都超過99%以上，其中還含有錳、硅等合金，所以密度稍微高于鋁的密度。

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系鋁卷：代表產品是2024，密度為2.78g/cm，該系列鋁卷的銅合金含量高，所以密度也比較大。

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系鋁卷：密度為2.73g/cm，該系列鋁卷內部含有錳合金。

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

　　4. 5系鋁卷：密度為2.68g/cm，該系列鋁卷內部鎂合金含量高，而鎂合金的密度要低于鋁的密度。

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系鋁卷：密度基本上在2.7g/cm附近，該系列鋁卷內部含有鎂合金和硅合金。

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.

　　總的來說，鋁卷的密度一般在2.68g/cm-2.78g/cm之間。

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