6005 Aluminum Alloy vs. 6005A Aluminum Alloy

6005A aluminum alloy is a medium-strength wrought alloy developed based on AA6005 . It is characterized by excellent extrusion performance, online quenching capability during extrusion, and corrosion resistance. Here is a summary of their main similarities and differences.


  • Both belong to the 6000 series aluminum alloys, mainly composed of magnesium and silicon, strengthened by heat treatment.
  • Both exhibit superior corrosion resistance, formability, strength, and weldability, suitable for various applications.
  • They possess excellent bending performance, although they are not recommended for frequent overloading or impact applications.
  • Easily undergo brazing and welding in commercial applications, though welding heat can reduce strength.
  • Excellent corrosion resistance and enhanced surface treatment properties.


  • 6005 aluminum alloy contains high silicon content, lowering the melting point and improving extrusion performance. 6005A aluminum alloy contains more chromium and additional manganese to reduce stress corrosion risk and enhance toughness. The additional manganese increases extrudability and strength.
  • While generally similar in overall mechanical performance, slight differences in alloy element content and processing techniques may lead to slightly different strength, plasticity, and mechanical performance under specific conditions.
  • 6005 6005A alloys share similar properties with 6106 and 6005 6005A alloys and are sometimes interchangeable. However, 6005 6005A alloys exhibit superior extrusion performance, and 6005A can even replace 6061 due to its better extrudability and surface appearance.

6005 6005A aluminum rods are among our featured products. If their characteristics do not meet your project's requirements, we also offer other rod materials from the 6000 series, such as 6061 aluminum rods, 6005 6005A aluminum rods.
