EN-MC32110 (MgZn6Cu3Mn) Magnesium
EN-MC32110 magnesium is a magnesium alloy. Cited properties are appropriate for the T6 temper. To achieve this temper, the metal is solution heat-treated and artificially aged until it meets standard mechanical property requirements. MC32110 is the EN numeric designation for this material. MgZn6Cu3Mn is the EN chemical designation.
It has a very low embodied energy among magnesium alloys. In addition, it has a very high density and a very high electrical conductivity.
The graph bars on the material properties cards below compare EN-MC32110 magnesium to other magnesium alloys (top) 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.
