Sintered 6061 (Axx-6061) Aluminum

Sintered 6061 aluminum is an otherwise-unclassified alloy of aluminum. It can have the lowest tensile strength among the otherwise unclassified aluminums in the database.

The properties of sintered 6061 aluminum include six 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 6061 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.
