The difference between aluminum sheet T5 and T6 by xuanxuan geng

Basic Information:
  • The forming temperature of the 4 x 8 aluminum sheet extrusion profile is 460 ~ 460 degrees, and the temperature after quenching is generally required to be 200 degrees. Through high temperature extrusion, the solution heat treatment (quenching) is followed by air cooling in artificial aging state (T5); through high temperature cooling extrusion process, water cooling in artificial aging state is then performed (T6).

    Aluminum quenching suddenly drops from high temperature to low temperature quenching. For example, steel knife blades should be quenched in water, only hard and sharp. Aluminum quenching has both water-cooled quenching and air-cooled quenching. The 6063 aluminum building is air-cooled and quenched. The quenched aluminum is aged in an aging furnace for a certain period of time, and the internal crystals of the aluminum are rearranged, and the mechanical strength is significantly improved.
    Air cooling, T5 is forced extrusion, T6 is water cooling, and the hardness increases after water quenching. However, the diamond-shaped aluminum plate needs to be bent, try not to reach the T6 state,
    Some people think that the difference between the 1/8 aluminum sheet T5 and T6 is only part of the difference in cooling speed, not the air cooling water. The difference between the cooling rates of air cooling is large enough to achieve the effect of T6, on the contrary, the cooling rate of water cooling is not large enough, and it can only achieve the effect of T5.
    In fact, the T6 state can be quenched online (water or air) or offline (quenched with a quenching furnace), but it depends on the customer's requirements and the product specifications of the aluminum foil manufacturer.
