Why 6061-T6 bar is widely used

6061-T6 combines moderate-to-high strength, good machinability, good corrosion resistance and broad availability. It is not the strongest aluminum alloy, but it is often the easiest practical choice for many machined parts.

Common buyer questions

  • Round bar, flat bar or square bar?
  • What diameter or section size is required?
  • Do parts need saw cutting before delivery?
  • Is T6 sufficient, or is a different temper required?
  • Are tolerance and surface requirements standard or custom?

When to choose another alloy

If the part needs higher strength, compare 7075. If welding is the main concern, discuss the welded strength requirement. If marine corrosion is the main issue, 5xxx-series material may be more suitable.
