6063-T5 aluminum alloy is air-cooled, with easy control of deformation coefficient and moderate hardness, while 6060-T66 aluminum alloy is strengthened by a special process on the basis of T6, with higher hardness, stable performance and small deformation. 6060-T66 aluminum alloy has higher silicon content than 6063-T5, and also contains small amount of copper and magnesium, which makes it have better strength and corrosion resistance. After solution heat treatment and artificial aging treatment, 6060-T66 aluminum alloy has higher strength and average mechanical properties than T6 under 20-30Mpa condition [T66 is under T6 (solution strengthening + full artificial aging)] condition, and then strengthened mechanical properties by a special process. Compared with 6063-T5, 6060-T66 aluminum alloy has smoother composition, higher precision, stronger anti-aging ability, and higher reliability.
