The choice of alloy is principally determined by the purpose for which the material is required, its qualities and the ability to work with it. The table below contains information about corrosion resistance, the ability to machine and suitability for anodising for different alloys.
The most common alloys, according to EN, are as follows: |
Round tube
Square tube
Rectangular tube | 6063 T6, 6082 T6, 2007 T4
| Flat bar
Square bar
Hexagon bar | 6063 T6, 6082 T6, 6012 T6, 2007 T6, 7075 T6 | | Round bar | 6063 T6, 6082 T6, 6012 T6, 2007 T4, 2011 T6, 2014 T6, 2017A T4, 7020 T6, 7022 T6, 7075 T6 | | Profiles | 6063 T6, 6082 T6 | | Plate and sheet | 1050A 0/H111, 1050A H24, 5005 H24, 5754 H22, 5754 H24, 5083 0/H111, 6082 T6, 2014 T6, 2017A T4, 7020 T6, 7022 T6, 7075 T6 |
