Properties and uses
of STIHL 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.
