Magnesium Alloy Computer Shell, Used For Lenovo Tablet Computer, Laptop Computer Shell
Is magnesium good for laptop?
Magnesium, an alternative to aluminum, is used as a primary alloy for an increasing number 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.
What is the advantage for magnesium alloy?
The advantage of magnesium alloys to be used in such applications is their light weight, high strength-to-weight ratio, high stiffness-to-weight ratio, castability, machinability, and great damping.
What is AZ91D?
Alloy AZ91D is the most widely used magnesium die cast alloy and has an excellent combination of mechanical properties, corrosion resistance, and castability. Corrosion resistance is achieved by enforcing very strict limits on three metallic impurities—iron, copper and nickel.
