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.
What is the composition of magnesium alloy?
The following table shows the chemical composition of magnesium AZ31B alloy….Chemical Composition.
| Element | Content (%) |
|---|---|
| Magnesium, Mg | 97 |
| Aluminum, Al | 2.50 – 3.50 |

What is AZ91 magnesium?
AZ91 alloy is the most popular material among cast magnesium alloy due to relatively high strength, excellent corrosion resistance, and good cast-ability.
What are Mg 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.
What elements are used in AZ91?
The chemical composition of the ingot metallurgy AZ91 alloy used in the present work was 9.0% aluminium, 0.80% zinc and 0.25% manganese.
What is AZ31B?
AZ31B is a wrought magnesium alloy with good room-temperature strength and ductility combined with corrosion resistance and weldability. AZ31B finds application in wide variety of uses including aircraft fuselages, cell phone and laptop cases, speaker cones and concrete tools.
