Our use of aluminum alloys 6063 and 6061 for the tubes used for facade cladding is very deliberate. First, these materials have amazing extrudability, so they can be formed into the customer’s preferred profile and size. Their corrosion resistance is also good, and this supports the need for durability. Regarding mechanical properties, these alloys give the user some of the best combinations. If you are looking for strong and heat-treatable facade cladding, you can pick 6061 aluminum. Go for 6063 aluminum if your focus is on a wide range of surface finishes and the formability of the aluminum tubes for cladding.
