What are the differences between 5-series and 6-series aluminum alloys?
1 Answers
5-series and 6-series aluminum alloys mainly have the following differences: 1. 5-series aluminum alloy: The main alloying element of 5-series aluminum alloy is Mg. Due to the difficulty in nucleation of precipitation phases, this series of alloys cannot be strengthened by heat treatment and usually achieve increased mechanical strength through work hardening. 2. 6-series aluminum alloy: The main elements of 6-series aluminum alloy are magnesium and silicon, with the primary strengthening phase being Mg2Si, which can be strengthened through heat treatment. This is the most significant difference between the two—non-heat-treatable strengthening versus heat-treatable strengthening. Additional information: Aluminum alloys are a general term for alloys based on aluminum. The main alloying elements include copper, silicon, magnesium, zinc, and manganese, while secondary alloying elements include nickel, iron, titanium, chromium, lithium, etc.
