What is the difference between 6063-T5 and 6061-T6 aluminum profiles?
At present, microstructure and mechanical properties of joint changes have some preliminary research on the welding of 6000 Aluminum Alloy, Department of the welding joint part of the alloy softening phenomenon is more serious, the main reason is the influence of softening joint welding thermal cycle of reinforcement particles occurred in aging and coarsening. The above research mainly concentrated in the softening behavior of welding, microstructure and heat affected zone of alloy, but on the 6063 Aluminum Alloy changes the mechanical properties of welding joints and welding thermal cycle and the relationship between the effect of artificial aging is also a lack of detailed research. The T5 condition is aging and natural cooling! The coefficient of deformation is small and easy to control! General hardness! T6 status is water cooled! Large coefficient of deformation! Not easy to control! High hardness!
6063 Aluminum Alloy belongs to Aluminum Alloy heat treatment, the main alloying elements as magnesium and silicon, the main strengthening phase is Mg2Si, with moderate strength, high corrosion resistance, no stress corrosion cracking tendency, good welding performance and corrosion resistance of weld zone constant etc.. The aluminum alloy has wide quenching range and low sensitivity to quenching temperature, and the thin-wall parts can be realized by wind quenching (strong wind cooling). Alloys are widely used in the frame and load-bearing panels of the construction and automotive industries. There is a relatively large tendency of over ageing in the welding process of this alloy. The direct reason is that the strengthening phase has been changed by the temperature.
T6 treatment of aluminum alloy is solid solution treatment and artificial aging treatment. Aluminum alloy with different components can be treated with T6 as the solution is treated by heat treatment. However, the specific technological parameters vary according to the composition, such as solid solution temperature and aging temperature. 6061 of the T6 process is: solid solution treatment temperature of 530 degrees, artificial aging to make T6, the state is plate 160 degrees, bar and 80 thickness above plate 175 degrees.
