6060 - T5 Extrusions

Aluminium alloy 6060 is a medium strength heat treatable alloy with a strength slightly lower than 6005A. It has very good corrosion resistance and very good weldability plus good cold formability especially in temper T4. It is commonly used alloy for very complex cross sections and has very good anodizing response.

Applications
Alloy 6060 is typically used for extrusions with complex cross sections and/or requiring anodising:
~ Architectural sections for windows, doors, curtain walls
~ Interior fittings, frame systems, lighting, ladders, railings, fences
~ Heat sink sections, electronic modules, electro motor housings
~ Flexible assembly systems, special machinery elements
~ Truck and trailer flooring, pneumatic installation, railway, inside applications
~ Irrigation, heating and cooling pipes
~ Furniture, office equipment.
