Magnesium Investment Casting

Magnesium investment casting produces complex parts from one of the lightest structural metals. BRK Metal casts magnesium parts to customer drawings for applications where weight is critical.

Properties of Magnesium

With a density of about 1.8 g/cm³, magnesium weighs about two-thirds as much as aluminum and about a quarter as much as steel. Pure magnesium has low strength, so parts are made from alloys. AZ91, AZ63 and WE54 are well-known casting alloys.

• High specific strength
• Good vibration damping
• Good machinability
• Good electromagnetic shielding
• Recyclability

Process Control in Magnesium Casting

Molten magnesium reacts with oxygen and with ceramic mold materials. Melting and pouring therefore need protective measures, and the shell and process must suit the metal. This is why not every foundry offers magnesium investment casting.

Why Investment Casting for Magnesium?

Investment casting produces thin, complex, lightweight parts as one piece. Replacing an assembly with a single casting can reduce both weight and assembly work.

Applications

Magnesium parts are used in defense, automotive and aerospace work, and in equipment that needs light housings.
