Magnesium: appliions and uses-Metalpedia - Asian …

Magnesium is the lightest of all light metal alloys and therefore is an excellent choice for engineering appliions when weight is a critical design element. It is strong, has good heat dissipation, good damping and is readily available. Its properties make it easy to weld, forge, cast or machine. It can be alloyed with other metals, making them more beneficial.

Sodium metal, as lithium, has also a tendency to dendritic growth . This fact coupled to its relatively low melting point (approx. 98°C) makes it an even less safe anode. However, magnesium or calcium seem to be less prone to dendrite formation, potentially due to the lower self-diffusion barriers of the adatom during plating [8–10].
