The 6060 alloy is a widely used extrusion alloy, suitable for applications that do not require special strength properties. Parts can be produced with a very good surface quality, suitable for numerous coating operations. Typical application fields include furniture, finishing materials, windows and doors, car-body finishing, façade construction, lighting columns and flagpoles, architecture and the food industry.
