EN-MC35110 (MgZn4RE1Zr) Magnesium
EN-MC35110 magnesium is a magnesium alloy. Cited properties are appropriate for the T5 temper. To achieve this temper, the metal is artificially aged until it meets standard mechanical property requirements. MC35110 is the EN numeric designation for this material. MgZn4RE1Zr is the EN chemical designation. Additionally, the British Standard (BS) designation is MAG 5. And the AFNOR (French) designation is G-Z4TR.
It has a moderately high density among magnesium alloys. In addition, it has a fairly high base cost and a fairly high embodied energy.
The graph bars on the material properties cards below compare EN-MC35110 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.
