Magnesium (Mg) is a lightweight metal and the eighth most abundant element in the Earth's crust, prized for its exceptional strength-to-weight ratio and excellent castability. It is widely used in aerospace, automotive, and portable electronics manufacturing, where weight reduction directly improves fuel efficiency, performance, or battery life. Engineers select magnesium alloys over aluminum or steel when the combination of low density with adequate stiffness and damping capacity is critical, though applications must account for its higher reactivity and corrosion susceptibility compared to more established light metals.
