Sintered 2014 (ACxx-2014) Aluminum
Sintered 2014 aluminum is an otherwise-unclassified alloy of aluminum.
The properties of sintered 2014 aluminum include nine common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare sintered 2014 aluminum 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.
