What Is Difference Between T4 T5 And T6 Status Of Aluminum Plate - China

What is the difference between the T4, T5 and T6 status of the aluminum plate The six series aluminum plate is an aluminum-magnesium-silico n alloy, and its representative grades are 6061 aluminum plate, 6063 aluminum plate and 6082 aluminum plate.

Different from the other 7 brand series aluminum plates, the state of the 6 series aluminum plates is mainly in the T state, and Mingtai Aluminum does more in the T4 and T6 states.

There is only one word difference.

What is the difference between these three states of aluminum plates? Before explaining the difference between these three states, the following two terms must be explained first:

Aging: The process of eliminating internal stress in metals.

Quenching: The metal is heated to a certain temperature and suddenly cooled to achieve the required hardness.

Moreover, the 2, 6, and 7 series aluminum plates can be quenched to increase the strength, so as to achieve the customer's ideal state.

T4 state means that after the aluminum sheet is extruded from the extruder (or rolled out of the rolling mill, and is heat-treated in the solid-melting furnace (quenching line)), it is naturally effective to a basically stable state and no longer undergoes cold working (straightening and leveling can be carried out without affecting Mechanical performance limit) products.

T5 state means that after the aluminum sheet is extruded from the extruder (or rolled out of the rolling mill, and heat treated in the solid melting furnace (quenching line)), the temperature is rapidly reduced by air cooling to achieve the required hardness.

Products that are no longer cold-worked (can be straightened and leveled without affecting the limit of mechanical properties).

The overall performance of T4/T5 is relatively close, and the surface hardness is average (Webster 8-12)

T6 state refers to the state in which the aluminum sheet is extruded from the extruder (or rolled out of the rolling mill, and heat treated in the solid melting furnace (quenching line)), and then water-cooled to instantaneously cool the aluminum sheet, and then perform low-temperature artificial aging.

Products that are no longer cold processed (can be straightened and leveled without affecting the limit of mechanical properties)

Usually T6 state, this will make the aluminum plate achieve higher hardness requirements (Webster's 13.5 hardness or more).

Air cooling takes a long time, usually 2-3 days, which we call natural aging; while water cooling is short, we call it artificial aging.

The main difference between the T4/T5 and T6 states is the strength.

The strength of the T6 state is higher than that of the T4/T5 state, and other aspects of the performance are similar.

In terms of price, due to the difference in production process, the price per ton of T6 aluminum sheet is 500-1000 yuan higher than that of T4/T5 aluminum sheet.

How to eliminate internal stress?

Mingtai aluminum sheet manufacturer introduced that in the production process of aluminum sheet, due to heat and extrusion, the density between the crystals is uneven, and the energy cannot be fully released.

The energy is stored in the aluminum sheet.

This energy is called internal stress.

Some users' production processes (such as heating, bending, deep drawing, stretching, etc.

) will release the internal stress of the aluminum plate, causing the aluminum plate to bend, wavy, and surface unequal, so the internal stress of the aluminum plate must be released first.

The process of eliminating internal stress is very simple.

After the aluminum plate is assembled, the manufacturer will add a process, which is the so-called stretching machine for stretching, which can release the energy inside the aluminum plate.

The state of the aluminum plate that eliminates internal stress is represented by the number Tx51, such as: 6061T651 aluminum plate, 6082T651 aluminum plate, etc.
