Description

This alkali earth metal is the lightest of the common structural metals, and it finds its most important application in the aerospace and the automotive industries. However, low hardness and tensile strength make pure magnesium unfit for most structural applications that involve high stress. So, magnesium is mostly used in alloys that include other structural metals that enhance its mechanical properties, such as aluminium. Magnesium burns in air producing a bright light, a chemical property that is still used in pyrotechnics today.

This material data has been provided by Matmatch.

"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.
