ACT1-2014 type III Sintered Aluminum
ACT1-2014 type III is sintered 2014 aluminum in the T1 temper. To achieve this temper, the metal is naturally aged until it meets standard mechanical property requirements. The graph bars on the material properties cards below compare ACT1-2014 type III to: otherwise unclassified aluminums (top), all aluminum alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
