EN-MC21110 (MgAl8Zn1) Magnesium

EN-MC21110 magnesium is a magnesium alloy. MC21110 is the EN numeric designation for this material. MgAl8Zn1 is the EN chemical designation. Additionally, the British Standard (BS) designation is MAG 1. And the AFNOR (French) designation is G-A6Z.

The properties of EN-MC21110 magnesium include two common variations. This page shows summary ranges across both of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare EN-MC21110 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.
