This is great tap perfectly designed for tapping the aluminum extrusions. This is the ideal tap when you are using end fasteners, or simply want to tap the end of the extrusion for a corner bracket, joining plate, end cap…etc. You will be able to tap the hole in one shot without having to back up to break the chip. Always use lubricant when tapping aluminum, WD-40 works fine as well.
AA 6063-T6 is an aluminium alloy, with magnesium and silicon as the alloying elements. The standard controlling its composition is maintained by The Aluminum Association. It has generally good mechanical properties and is heat treatable and weldable. It is NOT recommended to weld anodized aluminum.
