6061/6063 Aluminum Rectangle Tube

6061 Aluminum Rectangle Tube

Product Description:

We stock a mixture of 6061 and 6063 Aluminum Rectangular Tube. You will be shipped one or the other, depending on available stock. If you have a preference of one grade over the other, please let us know and we will be happy to oblige. Following are general descriptions of the two grades. 6061 is generally used in structural applications, where 6063 is primarily used in architectural applications.

6063 T-52 is an aluminum alloy, with magnesium and silicon as the alloying elements. Generally, it has good mechanical properties and is heat treatable and weldable. 6063 is mostly used in extruded shapes for architecture, particularly window frames, door frames, and roofs. It is typically produced with very smooth surfaces fit for anodizing. It displays very good corrosion resistance, medium fatigue strength and good cold formability.

6061 T-6 is a precipitation hardening aluminum alloy containing magnesium and silicon as its major alloying elements. 6061 has good machinability and good weldability. Typically, after welding, the properties near the weld are those of 6061-0, a loss of strength of around 80%. The material can be re-heat-treated to restore -T4 or -T6 temper for the whole piece. After welding, the material can naturally age and restore some of its strength. 6061 is one of the most common alloys of aluminum for general purpose use.
