What is the difference between the state of T5 and T6 in the

What is the difference between the state of T5 and T6 in the aluminum sheet?

The six series aluminum plate is the aluminum magnesium silicon alloy, its representative brand has 6061, 6063 and 6082. Different from the other 7 licensing department of aluminum, the state of the 6 series of aluminum to T state, the most is the T5 and T6 two states. Only difference, the difference between the two states where?

Before explaining the difference between T5 and T6 States, the user must first understand the following 2 terms:

Aging: the process of eliminating the internal stress of the metal.

Quenching: the metal is heated to a certain temperature suddenly cool to reach the demand for hardness. 6, 7, 2 series aluminum plate can be improved by quenching.

T5 refers to the state of aluminum extruded from the extruder after cooling the temperature decreased rapidly to achieve the required hardness (8--12 webster hardness). T6 refers to the state of aluminum extruded from the extruder with water to make instantaneous cooling aluminum, aluminum to achieve higher hardness (more than 13.5 webster hardness).

The use of air-cooled cooling time is relatively long, usually have 2-3 days, we call the natural aging, and the water cooling time is short, we call artificial aging. The main differences between the T5 and T6 states are in the strength, the strength of the T6 state is higher than that of the T5 state, and other aspects of the performance are similar. In the price, because of the difference between the production process, T6 state aluminum price per ton higher than the T5 state 500-1000.
What is the elimination of internal stress

Aluminum plate in the production process, because of heat and extrusion, resulting in uneven crystal density, energy is not fully released, the savings in the aluminum plate, this energy is called internal stress. The production process of some users (such as heating, bending, deep drawing and stretching) will release the internal stress of aluminum plate, aluminum plate, bending caused by moire, the surface is not equal, so you need to release the internal stress of the aluminum plate.

The process of eliminating the internal stress is very simple, after the aluminum plate to go down the line, the manufacturer will increase a process, using the machine to do a stretch of the aluminum sheet, you can release the energy inside the aluminum plate.

Eliminate internal stress of the aluminum state with digital Tx51, such as: 6061T651, 6082T651, etc..
