The difference between aluminum alloy 6063 and 6061
6061 contains more alloying elements than 6063. The main alloying elements of 6063 aluminum alloy are magnesium and silicon.
The aluminum profile of 6061 is better than that of 6063 in strength and cutting performance, and has good oxidation resistance.
But in terms of plasticity, 6063 aluminum is better, it can make the material to achieve higher precision; The 6063 has higher tensile strength and yield strength, and shows better fracture toughness.
Enclosures For Pcb, Power Supply Box are made by 6063 instead of 6061.
