Processing technology of 6061 aluminum bar

Heat treatment

Solution heat treat at 990 F for adequate time to allow for thorough heating and then water quench. Precipitation hardening is done at 320 F for 18 hours and air cool, followed by 350 F for 8 hours and air cooling.


The alloy is capable of being hot forged at temperatures in the range of 900 F to 750 F.

Hot working

Hot working may be done in the temperature range of 700 F to 500 F.

Cold working

Cold working in the O temper condition is readily performed. The alloy is notably less easy to cold form in the T 4 and T 6 tempers.


Annealing should be done at 775 F for 2 to 3 hours followed by controlled cooling at 50 f per hour down to 500 F, then air cool.


The aging precipitation heat treatment is done at 350 F for 8 hours followed by air cooling. This produces the T6 temper.

Performance characteristics of 6061 aluminum bar

From most angles, 6061 aluminum is the most commonly used aluminum alloy. Because of its high strength, high toughness, corrosion resistance, heat treatment ability, relatively easy processing and welding ability, it is specified in most applications.

  • The strength of 6061 aluminum bar is close to that of steel, but its weight is much lighter. It is a strong and durable alloy. It is easy to drill, machine and saw.
  • The main alloy components of 6061 aluminum are magnesium and silicon, so it has strong corrosion resistance, moisture resistance, stress resistance and crack resistance. This means that this material type is easy to form and weld.
  • This alloy can be easily anodized and has good molding and finishing properties.
  • The machinability is good under the hard T4 and T6 conditions. It is obviously not easy to machine in the annealing and tempering state.
  • It is easy to cold work and shape under annealing conditions. Stamping, bending, spinning and drawing can be easily completed using standard methods.
  • 6061 has good machinability and good weldability. All commonly used welding techniques can be used for welding. Generally, after welding, the properties near the weld are the same as 6061-O, and the strength loss is about 80%. The material can be reheated to restore the T4 or T6 temper of the whole workpiece. After welding, the material will naturally age and recover some strength.
