Properties of Aluminum 6061 alloys

Aluminum 6061:

A combination of aluminum with both magnesium (about 1% by weight) and silicon (about 0.5% by weight) as its major alloying elements, blended with a range of other materials such as iron, chromium, zinc, and copper. It is one of the most common alloys of aluminum for general-purpose use.

Properties: 

  • Strong
  • Easy to weld
  • Good toughness
  • Excellent corrosion resistance
  • Can be anodized
  • Widely available

Physical properties of A6061 aluminum:

  • Density: 2.7 g/cm3
  • Melting point: about 580° C
  • Elastic modulus: 70-80 MPa
  • Poisson Ratio: 0.33

The 6061 aluminum alloy is one of the most common and versatile for extrusion. It is generally referred to as structural aluminum since its strength makes it ideal for structural applications. However, because of its good combination of properties, it can also be used in a variety of project types.
