Die Casting Magnesium Alloy Case For Night Vision Instrument
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.
Is magnesium better than aluminum for laptop?
Magnesium is generally easier to use than aluminum in terms of manufacturing, opening up new design capabilities for laptop and tablet makers. Unfortunately, it's also considerably more expensive as a metal.
What are magnesium alloys used for?
Magnesium alloys are used for both cast and forged components, with the aluminium-containing alloys usually used for casting and the zirconium-containing ones for forgings; the zirconium-based alloys can be used at higher temperatures and are popular in aerospace.
This product is the shell of night vision instrument, material is magnesium alloy. This product is customized according to customer requirements. If you also need it, you can provide me with the size drawings
