3.2581 (DIN 1725-2 : 1986-02) 3.2581 DIN 1725-2 : 1986-02 DIN 1725-2 : 1986-02 replaced by DIN EN 1676 : 1997-02 and DIN EN 1706 : 1998-06 Replaced Germany EN AC-Al Si12(a) 2.1 1)
1) Remark: G-AlSi12 is an eutectic alloy with excellent casting characteristics. It has a medium strength but good plasticity, is weather and corrosion resistant. The alloy is suitable for difficult shapes, thin-walled, impact loaded cast parts. Application: devices, machines, vehicle, ship and apparatus engineering, housing, impellers, rib body, equipment support, filter bodies, facade panels
