Extruded Alloy Hardness 

When specifying 6063 aluminum alloy, we recommend a hardness indicator of -T5. Although -T6 is harder (providing improved machinability) it requires water quenching as the section is extruded which can result in warping and loss of tolerances, and is therefore deemed incompatible with the Fabfin process.
