The difference between 6063T5 and T6 status
It is cooled by a high-temperature molding process and then subjected to artificial aging. It is suitable for products that are artificially aged after being cooled by a high-temperature molding process without cold working (straightening and leveling, but not affecting the limit of mechanical properties).
Tensile strength (MPa) 160
Yield strength (MPa) 110
Hardness (HW) ≥8.5
The state of artificial aging after solution heat treatment is suitable for products that are not subjected to cold working after cooling in a high-temperature forming process (straightening and leveling, but not affecting the limit of mechanical properties)
Tensile strength (MPa) 205
Yield strength (MPa) 180
Hardness (HW) ≥11.5
Although the two states are different in definition, there is not much difference between the 6063 alloys, mainly in the difference of mechanical properties, considering the use of the product, if the requirements on strength or force If it is high, you can choose the state of T6. If it is not force, you can choose T5 state.
