The key advantages of Mg (Radha and Sreekanth 2017)

Benefits	Details
Low density	Mg density (1.738 g/cm3) is nearly equivalent to cortical bone density (1.75–2.1 g/cm3)
High specific strength	The strength-to-weight ratio of approximately 130 kN m/kg
High damping capacity	Mg has the highest energy absorption capacity of any metal and can be used in load-bearing applications
High machinability and dimensional accuracy	Mg is the simplest structural metal to machine and it is easy to accomplish steady final dimensions. As a result, advanced models are easily producible, which are critical for the complex shapes often required for medical applications
Less stress shielding	Since Mg density is very close to that of bone, stress-shielding issues for many orthopaedic implants can be greatly reduced
Good biocompatibility	Mg is a biocompatible mineral that has been found to speed up bone growth
Good safe degradation	Mg corrosion in the body would eventually lead to complete breakdown, thus it would be good for patients to be exposed to an implant in the body for a short period
