6061 alloy aluminum coil belongs to 6000 series alloy aluminum coil. 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.

The main alloying elements of 6061 alloy are magnesium and silicon, and Mg2Si phase is formed. If it contains a certain amount of manganese and chromium, it can neutralize the bad effect of iron; Sometimes a small amount of copper or zinc is added to improve the alloy
Without significantly reducing its corrosion resistance; There is also a small amount of copper in the conductive material to offset the adverse effects of titanium and iron on conductivity; Zirconium or titanium can refine grains and control recrystallization structure:

In order to improve the machinability, lead and bismuth can be added. In Mg2Si, the mg / Si ratio is 1.73. In the heat treatment state, Mg2Si is solid melted in aluminum, so that the alloy has the function of artificial age hardening.

6061 – t651 is the main state of 6061 alloy. It is a high-quality aluminum alloy product produced by heat treatment and pre stretching process. Although its strength cannot be compared with 2xxx series or 7xxx series, its magnesium and silicon

The alloy has many characteristics, such as excellent processing performance, excellent welding characteristics and electroplating, good corrosion resistance, high toughness, no deformation after processing, compact material without defects, easy polishing and coloring film capacity

Easy and excellent oxidation effect.

Representative applications include aerospace fixtures, electrical fixtures and communication fields. They are also widely used in automatic mechanical parts, precision machining, mold manufacturing, electronics and precision instruments, SMT and PC boards Solder carrier, etc.

Application of 6061 aluminum plate roll

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)
  • 6061 alloy aluminum coil for ACP
