Magnesium is the lightest structural material at about 1.8 grams per cubic centimeter. Magnesium is the 8th most abundant element in the earth's crust. It occurs naturally in dolomite, magnesite, carnallite and chloride (sea water). Magnesium is produced from seawater, brine and magnesium-containing minerals, and its reserves are unlimited.
Magnesium is 75% lighter than steel and 33% lighter than aluminum, provides component and functional integration, and provides high dimensional stability for improved fit and finish.

Magnesium vs Steel
Magnesium is 75% lighter than steel and offers the benefits of component consolidation/integration, significantly lower tooling costs, high thermal conductivity, complex thin-wall near-net shape, and excellent dimensional stability/repeatability.
Comparing Magnesium and Plastic
Compared with steel, magnesium has higher strength and has the advantages of high stiffness, high energy absorption capacity, high application temperature, and large thin-walled near-net-shape castings.
Comparing Magnesium and Aluminum
Compared with aluminum, magnesium is 33% lighter and has the advantages of superior machining, large thin-walled near-net-shape castings, higher mechanical properties and stronger overall corrosion resistance.
Our Die Cast Magnesium Alloys
We help our customers select alloys based on the environment in which the part will function in the performance requirements of the assembly.
AZ91D: The alloy most commonly used in high pressure die casting. Has a good strength to weight ratio, very good corrosion resistance and excellent castability. This alloy is typically used in power train and mechanical components where toughness is more important than deformability.
AM60B: Automotive die castings commonly used in safety components such as dashboard structures and seat frames. This alloy has excellent ductility, energy absorbing properties, strength and castability.
AM50: This alloy has a lower aluminum content than AM60, which further increases ductility at the expense of slightly lower strength and slightly lower castability. It is typically used where performance requirements require elongation in excess of AM60.
Note: For applications such as power train components operating at temperatures above 120 degrees Celsius (such as automatic transmission housings), there is a large selection of magnesium alloys. These alloys are designed to operate at higher temperatures without "creep", maintaining bolt tension and seal surface flatness. Meridian recommends discussing this issue with our engineering team to review available options.
