What are usual tempers for 6061 aluminum sheet?

6061 aluminum sheet is one of the most widely applied aluminum alloy in various industries. Boasting excellent weight advantage and corrosion resistance, it can be used in automobile bodies, cake molds etc. Generally there are three tempers in its production: T6, F and O.

T6 ranks number on in adoption for production of 6061 aluminum sheet. At this state thicker sheets go through processes including quenching, cutting, stretching, aging treatment, sawing, polishing and packaging. These processes last about 10 days. After experiencing a solid solution heat treatment 6061 aluminum sheet can be aligned and flattened directly without cold treatment. Its mechanical property will not be change because of the steps above. F refers to free processing state. It’s suitable for the forming process of special products which meet requirements about work hardening and hot treatment. F state has a short production period. Normally the whole process finishes in three days. There’s no specification demands about F state, because clients usually put 6061 aluminum sheet at this state into further process like hot treatment to obtain desired states. It has lower price because of this. O state refers to full annealing of aluminum sheet. This type of sheet has lowest strength of all states. O state fits thin aluminum sheet of 8.0mm thick or below. The production processes include cold rolling to wanted thickness, stretch bending, flattening, cleaning, full annealing, cutting and packaging etc, which last a little shorter than the production period of T6 state.
