The main alloying elements of 8011 aluminum strip are silicon (Si) and iron (Fe), with a silicon content of 0.5 – 0.9% and an iron content of 0.6 – 1.0%. The remaining is mainly aluminum, along with trace amounts of other elements such as copper, magnesium, and manganese.
In the O temper (fully annealed), the tensile strength is 70 – 110 MPa, the yield strength is 30 – 50 MPa, and the elongation is 20 – 40%. These properties make it have good formability and ductility, which is conducive to the processing and manufacturing of pipes.
The thickness of 8011 aluminum strip for pipes is usually in the range of 0.1 – 1.0 mm, and the width can be 10 – 300 mm. For example, some common thicknesses are 0.21 mm with a tolerance of ±0.02 mm, and widths can range from 20 – 300 mm with a tolerance of ±0.2 mm.
