Properties and uses

standard alloys

Magnesium alloys for diecasting make it possible to produce components with low weight at competitive manufacturing costs. Thin walls, dimensional accuracy, short casting cycles and a long die service life are typical advantages of magnesium diecastings. Further advantages include the excellent machinability, good attenuation and (EMI) shielding properties.


High purity and advanced corrosion-proofing techniques allow our diecasting alloys to be used in corrosive environments, too.

EN-MB MgAl9Zn1(A) (AZ 91)
The commonest diecasting alloy with outstanding casting properties and high mechanical strength. Typical applications: automotive parts, computer components, parts for mobile phones, sports equipment, covers and housings, components for chainsaws, manual tools, household appliances, etc.

EN-MB MgAl5Mn (AM 50) and EN-MB MgAl6Mn (AM 60)
This alloy is characterized by particularly high elongation and energy absorption with high mechanical strength and good casting properties. Typical applications are to be found in automotive engineering: seat frames, steering wheels, dashboard supports, fanwheels, etc.

EN-MB MgAl2Mn (AM 20)
The high elongation combined with high impact strength is characteristic of this alloy. It is therefore typically used for safety components in motor vehicles.
