What is T6 heat treatment for Aluminium?

T6 Heat Treatment is a two-phase process which is applied to Aluminium, Copper, or Silicon alloys to increase the strength of the alloy by as much as 30\%.

What is aluminum 6061 T6 used for?

6061 Aluminum Sheet The T6 refers to the temper or degree of hardness, which is achieved by precipitation hardening. This grade has a good strength-to-weight ratio and is also heat-treatable. With great formability and weldability, it is used for engineering and structural applications, boats, furniture, and more.

CAN 6061 Aluminum be heat treated?

Aluminium / Aluminum 6061 alloy is heat-treated at 533°C (990°F) for a sufficient period of time followed by quenching in water. The precipitation hardening process can be performed at 160°C (320°F) for 18 h followed by air cooling.

How do you heat treat 6061 to T6?

Solution heat treatment is done by raising the alloy temperature to about 980 degrees F and holding it there for about an hour. The purpose of this is to dissolve all the alloying elements in a solid solution in the aluminum.

What does T6 heat treatment do?

The T6 thermal cycle consists of a solution heat treatment followed by a water quenching and then an age hardening (or precipitation hardening). The solution heat treatment leads to the dissolution of intermetallic phases and the spheroidization of eutectic Si with a resulting improvement of alloy ductility [9,10].

Which is the most important and useful alloy of Aluminium?

6061 alloy is one of the most commonly used general-purpose aluminium alloys. 7000 series are alloyed with zinc, and can be precipitation hardened to the highest strengths of any aluminium alloy (ultimate tensile strength up to 700 MPa for the 7068 alloy).

Why is aluminum heat treated?

While not all aluminum alloys benefit from heat treatment, we can heat-treat several alloys to increase the ease of forming or the strength of the finished product. Unlike steel or iron, aluminum requires rigid heat control to achieve optimal results, so special equipment is often required.

What is T6 heat treatment process?

What is solution heat treatment of aluminum?

Solution treatment involves heating the aluminum to a temperature of 430-540°C (800-1000°F), at which alloying constituents are taken into solution (i.e., brought near their melting point) prior to a rapid quench.

How is 6061 T6 aluminum made?

To create 6061 T6 aluminum, a 6061-O aluminum billet is heated to more than 900˚ F, water quenched, then aged for hours at a lower temperature. This is the foundation of the artificial aging distinction characteristic of T6. How is the Yield Strength of 6061 Aluminum Improved by a T6 Temper?

What is a T6 condition for aluminum?

Following this aging, the parts are now at a T6 condition. In general, T6 is the most common temper for aluminum, and because 6061 aluminum is often used in heavy-duty structures, the strength and limited formability of metal at that temper is important.

Is 6061 aluminum heat treatable?

Magnesium and silicon are the major alloying elements in this metal, and 6061 is generally strong and corrosion resistant. It is heat treatable and crack resistant when stress is removed. When 6061 aluminum is brought to us off the shelf, it’s most often in O condition, which is its softest, most pliable state.

What is 6061 grade aluminum used for?

6061 is one of the most commonly used grades aluminum grades in the world. Whether it’s an aluminum sheet, aluminum plate, aluminum bar, or aluminum angle, 6061 is the choice for a wide range of applications, including boats, furniture, and structural applications.
