The word temper refers to the combination of hardness and strength imparted to aluminum by mechanical or thermal treatments.
Penn provides shapes, pipe and tubing in all standard tempers.
All aluminum alloys, regardless of product form, are classified as either heat-treatable or
Those alloys classified as nonheat-treatable develop maximum strength characteristics through cold work (strain-hardened) after extruding.
The nonheat-treatable alloy extruded by Penn aluminum is the 3xxx series.
Heat-treatable alloys attain their maximum strength through controlled heat treatment. Many high strength aluminum
alloys come from this group, one of which is the 6xxx series extruded by penn.
The Temper Designation System lists the modification methods applied to

treated; thermally treated to produce stable tempers other than F, O, or H.
A complete alloy-temper designation reads like this: "6063-T5." This designation indicates a particular
alloy of the 6xxx series (Mg and Si), which is thermally treated by being cooled from an elevated
temperature and artificially aged.
Penn Aluminum can provide aluminum shapes, pipe and tubing in all standard tempers.
Special tempers can be provided for specific applications as designated by the customer.
