Characteristics

6063 was developed for and has become the most important extrusuion alloy. It possesses moderate strength and has excellent finishing characteristics. For these reasons, 6063 has become the prime architectural alloy and its response to a wide variety to surface finishes further demonstrates its versatility. The corrosion resistance is very good and the grade is easily welded and brazed, and is heat-treatable as well.
