Aluminium alloy 6106 is an extrusion alloy designed to provide optimum combination of mechanical properties, complexity of shape, minimum section thickness and good surface finish together with the good resistance, weldability and formability associated with the 6000 series alloys. Very complex shapes are possible which are not obtainable with stronger alloys such as 6182.
(6000 series alloys achieve their properties by thermal treatment which can be adjusted to provide combinations of strength and formability conditions with good corrosion resistance and weldability. Because the properties are obtained by thermal treatment, fusion welding reduces the non-welded properties by up to 50%.)

Applications
Alloy 6106 is typically used for:
~ Structural applications
~ Ladders, pylons and towers
~ Railway Rolling Stock
~ Marine applications
~ Automotive structures
