6063 and 6061 alloy comparison

6063 and 6061 alloy comparison

AA 6063 is an aluminum alloy, with magnesium and silicon as the alloying elements.

The standard controlling its composition is maintained by The Aluminum Association.

It has generally good mechanical properties and is heat treatable and weldable.

It is similar to the British aluminum alloy HE9.

6063 is the most common alloy used for aluminum extrusion.

It allows complex shapes to be formed with very smooth surfaces fit for anodizing and so is popular for visible architectural applications such as window frames, door frames, roofs, and sign frames.

Alloy 6061 is one of the most widely used alloys in the 6000 Series.

This standard structural alloy, one of the most versatile of the heat-treatable alloys, is popular for medium to high strength requirements and has good toughness characteristics.

Applications range from transportation components to machinery and equipment applications to recreation products and custom durables.

6061 Alloy can be produced for use in standard and custom shapes, rod and bar products, and seamless and structural pipe and tube.
