We all know that aluminum extrusions are widely used in a wide range of applications. The primary element of the material is aluminum, with alloys such as magnesium, copper, zinc, and silicon added to form the composition. Aluminum extrusions are classified into various categories, including seven series based on alloy composition. Each series contains different alloying elements. Industrially, copper-based alloys are primarily aluminum-silicon, while 6-series aluminum extrusions, which contain a small amount of magnesium, are the most widely used. Today, we’ve reviewed the main features and applications of 6-series aluminum extrusions.
As mentioned above, 6-series aluminum extrusions are alloys primarily composed of aluminum and silicon. They are extruded at high temperatures to form a strengthening phase called Mg₂Si. There are many alloy grades for 6-series aluminum extrusions, with the most commonly used being 6463, 6262, 6201, 6082, 6063, 6061, 6010, 6009, and 6005. CNC machining manufacturers often use 6061 and 6063.
