Abstract (en)
[origin: EP0478479A1] This process consists in adding strontium to the said alloys before moulding. <??>It applies more particularly to magnesium alloys containing as main addition elements and on a weight basis 4 to 10% of aluminium and either up to 3% of zinc and/or up to 1% of manganese, or up to 1% of silicon and/or up to 1% of manganese, and which are employed especially for the manufacture of gearbox casings and of structural components of portable computers.
