6061 aluminum coils is the most versatile of the heat treatable aluminum alloys. Though less strong than most of the 2xxx and 7xxx alloys, 6061 aluminum coil provides an extensive range of mechanical properties and corrosion resistance and can be fabricated by many of the commonly used practices.  In the "O" temper or annealed condition, alloy 6061 aluminum coil has good formability.  In the T4 condition, fairly severe forming can be done; whereas, in the T6 condition, properties may be obtained by artificial aging.

6061 is a precipitation-hardened aluminum alloy, containing magnesium and silicon as its major alloying elements. Originally called "Alloy 61S", it was developed in 1935. It has good mechanical properties, exhibits good weldability, and is very commonly extruded (second in popularity only to 6063).It is one of the most common alloys of aluminum for general-purpose use.

It is commonly available in pre-tempered grades such as 6061-O (annealed), tempered grades such as 6061-T6 (solutionized and artificially aged) and 6061-T651 (solutionized, stress-relieved stretched and artificially aged).Temper:O T6 T651 etc.

Performance of 6061 aluminum coil

1,6061 aluminum-magnesium alloy series of high-plastic alloy, heat treatment to strengthen, high impact toughness;

2, has excellent thermoplastic, welding performance and corrosion resistance;

3, no deformation after processing, the surface is very smooth, and easy anodizing and coloring;

4, excellent interface characteristics, high strength, good usability, strong corrosion resistance.

6061 aluminum coil application:

It’s common for 6061 aluminum coil to be used for structural components, worm gears, electrical connectors, electrical fittings, marine fittings and hardware, marine components and for heavy duty structures that need good resistance to corrosion and strength-to-weight ratio. When in the annealed state, this metal can be cold worked using a variety of standard methods. For instance, it can be deep drawn, stamped, drilled, tapped, cut and bent.

  • Truck bodies and frames
  • Screw machine parts
  • Structural components
  • Coated Aluminium Roof Tile

6061 aluminum is commonly used for the following:

♦construction of aircraft structures, such as wings and fuselages, more commonly in homebuilt aircraft than commercial or military aircraft. 2024 alloy is somewhat stronger, but 6061 is more easily worked and remains resistant to corrosion even when the surface is abraded, which is not the case for 2024, which is usually used with a thin Alclad coating for corrosion resistance.

♦yacht construction, including small utility boats.

♦automotive parts, such as the chassis of the Audi A8.

♦some tactical flashlights

♦aluminum cans for the packaging of food and beverages.

♦SCUBA tanks (post 1995)
