In comparison with the relatively low strength of polymers, magnesium demonstrates a tensile strength that is much closer to that of natural bone. This means that these alloys are much more suited for use in load-bearing mechanical medical devices. Magnesium is also a naturally occurring element in the body, with proven biocompatibility.

1. Introduction. Magnesium is the lightest structure among all engineering materials. Mg has the lowest density of 1.74 g/cm 3 compared to the density of Aluminium (Al), Titanium (Ti) and steel, which are 2.71, 4.5 and 7.8 g/cm 3, respectively. The low density, high specific strength, and biodegradable nature make them an attractive …

In this context, magnesium is lighter in weight than aluminum. It has a good strength–density ratio. Therefore, magnesium alloy is slowly replacing aluminum alloy. The density of magnesium is 1.739 g/cm 3 whereas aluminum has 2.7 g/cm 3. Thus, the weight of the magnesium is almost two-third that of aluminum.

What is Magnesium? Magnesium is the lightest of all commonly used structural materials with a density of 1.7g/cm 3 (106.13lb/ft 3) approximately 1/3 lighter than aluminum. It is the 8th most abundant element in the earth's crust however, it is rarely found in its pure form due to the fact that it bonds with other elements easily.
