There are many advantages to using magnesium and its alloys With the lowest density of all commercial casting alloys magnesium is 33 percent lighter than aluminum and 75 percent lighter than steel Despite the lower density magnesium alloys have a comparable strength to weight ratio to aluminum Magnesium and its alloys also have a high vibration damping capacity making them an ideal material choice for many high speed applications Electromagnetic interference reduction is another desirable quality that magnesium can offer as a material In an increasingly environmentally conscious world the full recyclability and ample availability of the metal also make it a suitable choice
