Aluminum tube is an aluminum alloy tubular product, which is divided into seamed aluminum tube and seamless aluminum tube.

Commonly used aluminum tube materials are 6 series, 3 series, 5 series, 7 series, 2 series and 1 series.
Among them, the 6 series aluminum tubes represent 6063, 6061, 6005, 6082 materials. Aluminum tubes are divided into these 4 materials according to the composition of silicon and magnesium, among which 6061 aluminum tubes are mostly used for industrial machining. 6063 is for general use with low hardness, 6005 is between 6061 and 6063, and 6082 is relatively hard.

The chemical composition of 6082 aluminum tubes follows the national standard GB/T3190-2012. The contents of various elements are:

Si Silicon: 0.7-1.3

Mg Magnesium: 0.6-1.2

Fe Iron content is less than 0.5, and generally Xinsheng manufacturers control it to be less than 0.2, which improves the conductivity.

Cu The copper content is below 0.1, a small amount of copper element plays a hardening role here to increase the hardness

Mn Manganese content is 0.4-1.0, manganese and magnesium complement each other, and the corrosion resistance increases.
