Al-Mg-Si alloys with high content of Fe-containing primary phases


One of the biggest challenges in recycling aluminum is the highly diverse composition of aluminum scrap. Iron in particular poses a problem, as it gradually accumulates through the recycling of secondary aluminum and is difficult to remove by metallurgical means. In aluminum alloys it tends to form coarse primary phases, most of which reduce ductility and have a negative effect on forming processes. What if these otherwise harmful iron-containing phases could not only be rendered harmless by alloy design and adapted processing, but could also be used to positively influence the microstructure in wrought Al alloys? For this purpose, Al-Mg-Si alloys are modified with high iron and manganese contents. The focus is on improving the mechanical properties by using the iron‑rich phases to set an optimized microstructure.
