Elongation of Common Magnesium Alloys

Magnesium alloys are known for their relatively low elongation at break compared to some other metals. Typically, magnesium alloys exhibit elongation values ranging from 2% to 20%, depending on the specific alloy composition and processing conditions.

The following table provides a comprehensive list of elongation at break values for common magnesium alloys.
