Basic Introduction of Aluminum Alloy 6061 T6
What is T6 Temper?
T6 tempering is a heat treatment process used to strengthen and harden certain alloys, especially aluminum alloys. T6 refers to artificial aging after solution heat treatment. The T6 process involves heating the material to high temperatures (typically around 500°C) and then quenching it in water or air for rapid cooling.
This process is called solution heat treatment, and it dissolves alloying elements into the aluminum matrix. Following solution heat treatment, the material is artificially aged by heating the material to a lower temperature for several hours, which results in the formation of a precipitate of strengthening material.
What is Aluminum Alloy 6061 T6?
Aluminum alloy 6061 T6 is a heat treated version of 6061 aluminum alloy and is a versatile material used in a wide variety of industries. The “T6” designation refers to the tempering process, where the material is heated to high temperatures, usually around 500°C, and then quenched in water or air to cool rapidly.
