The 6000 series aluminum alloys (mainly Al-Mg-Si alloys) are versatile and widely used due to their balance of strength, corrosion resistance, and good formability. They are typically heat-treated to enhance mechanical properties like tensile strength and hardness. The heat treatment process for the 6000 series usually involves solution heat treatment, quenching, and aging
6060
The 6060 alloy exhibits high thermal conductivity, making it suitable for heat exchangers and cooling systems. Good machinability is a hallmark of 6060 alloy. The T6 temper makes it easier to machine, as the material is harder and more stable.
6063
Often used for extrusion, this alloy offers excellent formability and surface finish, typically used in architectural applications.
6082
Moderate formability due to the higher strength of 6082 compared to other 6000 series alloys like 6060 and 6063. High thermal conductivity, although slightly lower than pure aluminum. The typical thermal conductivity is around 180 W/m·K, which is beneficial for applications like heat exchangers or automotive components where heat dissipation is critical.
6005
Even in the stronger T6 temper, 6005 maintains reasonable ductility, with elongation ranging from 10-12%, allowing it to be used in applications where some forming is necessary.6005 is commonly used in applications where parts require machining after extrusion or other fabrication processes.
