What Is Magnesium Die Casting?

Magnesium boasts the distinction of being the lightest structural material, with a density of approximately 1.8 grams per cubic centimeter. Moreover, it ranks as the eighth most prevalent element within the Earth's crust, naturally occurring in minerals such as Dolomite, Magnesite, Carnallite, and sea water Chloride. The production of magnesium derives from abundant sources such as sea water, brines, and minerals rich in magnesium, ensuring virtually limitless reserves.

In terms of material properties, magnesium outshines its counterparts by being 75% lighter than steel and 33% lighter than aluminum. It facilitates component and feature integration and exhibits remarkable dimensional stability, enhancing overall fit and finish.

Magnesium vs Steel

When juxtaposed with steel, magnesium stands out as 75% lighter, offering distinct benefits such as component consolidation and integration, notably reduced tooling expenses, exceptional heat conductivity, the ability to achieve intricate thin-walled near-net shapes, and superior dimensional stability and repeatability.

Magnesium vs Plastic

When comparing magnesium to plastic, magnesium exhibits greater strength and comes with advantages like superior stiffness, enhanced energy-absorbing capabilities, suitability for higher-temperature applications, and the capacity for producing large thin-walled near-net shape castings.

Magnesium vs Aluminum

In contrast to aluminum, magnesium is 33% lighter, offering distinct advantages such as enhanced machinability, the ability to produce large thin-walled near-net shape castings, superior mechanical properties, and heightened overall corrosion resistance.

Magnesium Alloy Castings We Produce

We assist our customers in selecting the appropriate alloy based on the operational environment and performance criteria of the component.

AZ91D: This alloy is the most commonly employed for high-pressure die casting. It boasts a favorable strength-to-weight ratio, excellent corrosion resistance, and outstanding castability. Typically, AZ91D finds application in powertrain and mechanical components where toughness takes precedence over deformation capacity.

AM60B: Widely used in automotive die castings, particularly for safety-related components like instrument panel structures and seat frames. AM60B offers exceptional ductility, energy-absorbing properties, strength, and castability.

AM50: Differing slightly from AM60 in its lower aluminum content, AM50 provides even greater ductility while experiencing a minor reduction in strength and castability. It is typically utilized in situations where performance requirements necessitate elongation properties surpassing those of AM60.

Note: For applications such as powertrain components operating at temperatures exceeding 120 degrees Celsius (e.g., automatic transmission housing), a wide array of specialized magnesium alloys is available. These alloys are designed to withstand higher temperatures without exhibiting "creep," thereby maintaining bolt tension and sealing surface flatness. Meridian recommends consulting our engineering team to explore the available options for such applications.
