Description

Aluminum AA 2011 is a popular age-hardenable alloy known for its free-machining characteristics and mechanical properties. It can be machined to very close tolerances while still maintaining a smooth and bright finish. Unlike other aluminum alloys, AA 2011 does not offer good corrosion resistance or weldability.

Equivalent Materials

This material data has been provided by AluKey,MakeItFrom.com.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
