The main alloying elements of 6061 alloy are magnesium and silicon, which is one of the most widely used aluminum alloys. It has medium strength, good corrosion resistance, and good oxidation effect, especially the alloy has an excellent response to hard oxidation. 6061 aluminum plate is widely used after heat treatment, and 6061 aluminum alloy thick plate is used in semiconductors, automated mechanical parts, precision machining, various mold manufacturing, fixtures and so on.
The difference between the three major states of 6061 aluminum plate:
The T6 state is the most used of 6061 aluminum alloy. In this state, 6061 medium plate is quenched by medium plate-medium plate slice-stretching machine-aging treatment-sawing machine-polishing-packaging. After the solution heat treatment, cold working is not required, and straightening and leveling can be performed, but the mechanical properties are not affected.
The F state is a free-machining state of 6061 aluminum alloy, which is suitable for products that have no special requirements for work hardening and heat treatment conditions during the forming process. The F-state production cycle is very short: plate cutting-sawing machine-polishing (or not polishing, according to customer requirements)-packaging, F-state mechanical properties are not specified, customers can heat-process the F-state according to their needs, production It can be used in the required state, and the corresponding price is also the cheapest.
The O state is the processed product with the lowest strength obtained by complete annealing of 6061 aluminum alloy. Applicable to 6061 aluminum alloy sheet below 8.0, its production process: cold rolled finished product thickness—drawing, bending, straightening and cleaning—complete annealing—flying shears (or drawing, bending and straightening finished products) —packing and storage, etc. less.
