2015/3/19· Aluminum, magnesium, and zinc are the most common alloys used in the die casting process, deciding which alloy is best is usually based on design specs. Magnesium alloys are the lightest of the commonly used structural metals used for die casting. are the lightest of the commonly used structural metals used for die casting.
2017/6/20· Magnesium, an alternative to aluminum, is used as a primary alloy for an increasing nuer of laptop designs. It’s lighter by volume than aluminum by approximately 30% (it’s actually the lightest structurally-used metal in the world), while having a greater strength-to-weight ratio.
