AM60B Magnesium vs. EN 1.1140 Steel
AM60B magnesium belongs to the magnesium alloys classification, while EN 1.1140 steel belongs to the iron alloys. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.
For each property being compared, the top bar is AM60B magnesium and the bottom bar is EN 1.1140 steel.
