The Difference Between Aluminum SheetT5 And T6

Aluminum sheet extrusion profile forming temperature is 460 ~ 460 degrees, general requirements after quenching temperature for 200.Through high temperature extrusion, after solution heat treatment (quenching) for artificial aging status of air cooling (T5);By high temperature cooling extrusion process, and then for artificial aging status of water-cooled (T6).

Aluminum quenching from high temperature suddenly drops to as low quenching, such as steel knife blades to be quenched in water, only hard and sharp, and both water-cooled aluminum quench hardening, there are air-cooled quenching. 6063 aluminum construction that is air-cooled quenching, after quenching the aluminum aging furnace aging on a certain time, the internal crystalline aluminum rearrange mechanical strength improved significantly.

Air-cooled, T5 is forcing the T6 is water-cooled after extrusion, after water quenching hardness is increased.But diamond plate aluminum sheet need bent, try not to T6 state,

Some people think that the difference between the aluminum plate T5 and T6 is only part of the cooling speed difference, not air cooling water. The difference between the cooling speed of air cooling is enough big, can also achieve T6 effect, on the contrary, water cooling rate is not big enough also only is the effect of the T5.

Actually T6 state can be either online quenching (water or air), can also be offline quenching (with quenching furnace quenching), but according to customer requirements and aluminum foil manufacturer product specifications.
