Role of Alloying Elements in 6061-T6 Aluminum
The main alloying elements in 6000 series aluminum are magnesium and silicon, forming the Mg₂Si phase. The presence of manganese and chromium helps offset the negative effects of iron. Small amounts of copper or zinc may be added to increase strength without significantly reducing corrosion resistance. Copper can also improve conductivity by counteracting the negative effects of titanium and vanadium. Zirconium or titanium refines grain structure and controls recrystallization, while lead and bismuth can enhance machinability.
The Mg/Si ratio in Mg₂Si is approximately 1.73, though maintaining this ratio in production is challenging. Most alloys therefore contain either excess magnesium or excess silicon. Excess magnesium improves corrosion resistance but reduces strength and formability, while excess silicon increases strength but reduces formability and weldability, with slightly improved resistance to intergranular corrosion.
