Ⅰ: 6061 aluminum sheet

Ⅰ-a: What is 6061 alloy metal aluminum sheet plate?

6061 alloy metal aluminum sheet plate belongs to 6000 series aluminum sheet. Alloy 6061 aluminum sheets are one of the most versatile and widely used heat-treatable alloys. 6061 aluminum alloy has excellent corrosion resistance, excellent machinability, weldability, and medium strength.


6061 t6 aluminum sheet has a high strength to weight ratio making it ideal for any application where parts need to be light.

6061 alloy aluminum sheet is a high-quality aluminum alloy product produced by the heat treatment pre-stretching process.

Although its strength cannot be compared with the 2xxx series or 7xxx series, its magnesium and silicon alloys have many characteristics and have excellent processing properties and excellent welding characteristics.

And electroplating, good corrosion resistance, high toughness, and no deformation after processing, the material is dense and defect-free, easy to polish, easy to paint film, excellent oxidation effect, and other excellent features.

6061 aluminum sheet in different temper based on customer’s need, with a wide thickness range up to 600mm.  In addition, an extra-wide aluminum sheet with a maximum width of up to 2650mm, is an ideal material for curtain walls.

Ⅱ: Specifications of 6061 aluminum sheets

Ⅱ-a: Here are five common tempers in 6061 aluminum sheet plate

  1. Heat treatment temper. 6061-T651 is a classic alloy processed by heat treatment, its state is suitable for further processing.
  2. F(free) temper. This temper of alloy has changeable mechanical properties.
  3. Annealed state. This state applies to the alloys that are fully annealed to obtain the lowest strength.
  4. Work hardening temper. The strength of alloys can be enhanced by work hardening.
  5. Solution heat-treated temper. This temper is in an unstable state, it also means the alloy is in a natural aging stage.

Ⅱ-b: 6061 aluminum alloy properties by temper

6061 bare aluminum sheet plate can be processed into varieties of tempers, such as O, T4, T6, T651, etc. Among them, T4 and T6 are the most common ones for their good machinability and weldability.

6061 aluminum sheet plate has a T651 temper, indicating it has been solution heat treated followed by a minimal stretching to reduce stresses in the material. The aluminum was then artificially aged to allow the alloying elements to precipitate out of the material giving our 6061-T651 aluminum plate immediate maximum strength.

Ⅲ: T4 and T6 of 6061 Aluminum sheet

6061 aluminum plate is one of the most widely used alloys in the heat-treatable alloy family. It can be used for bending under annealing conditions because the difference between yield strength and tensile strength is 10 Ksi and the elongation is up to 18%. However, bending capacity tends to decrease when increased to T4 and T6 tempering. It is not impossible to bend these hardened and tempered alloys, but great care is required and larger bending radii may be required to avoid cracking.

Ⅳ: What is  difference between 6061 Aluminum sheets and 6063 Aluminum Sheets?

6063 Aluminum Sheet is another commonly used Aluminum grade, usually compared to 6061 Aluminum Sheet. 6061 and 6063 are made of magnesium and silicon, which means they share many of the same properties. The difference between 6061 and 6063 is mainly in end-use. 6063 Aluminum Sheet is a common grade of customized extruded parts.

However, 6061 Aluminum Sheet is the most commonly used Aluminum in structural applications. Generally speaking, the strength of the 6061 Sheet is higher than that of the 6063 Aluminum Sheet (tensile strength range is 20 ~ 42KSI).
