EN AC-21000 (DIN EN 1706 : 1998-06) EN AC-Al Cu4MgTi EN AC-21000 DIN EN 1706 : 1998-06 DIN EN 1706 : 1998-06 replaced by DIN EN 1706 : 2013-12 Replaced Germany G-AlCu4TiMg EN AC-Al Cu4MgTi 2.1 1)
1) Remark: Material EN AC-Al Cu4MgTi is produced as sand, chilled and precision casting. It shows the following casting characteristics and properties: plasticity: acceptable heat crack resistance: insufficient pressure tightness: insufficient workability (casting condition): excellent corrosion resistance: insufficient decorative anodic oxidation: acceptable weldability: insufficient polishability:good strength at room temperature: excellent strength at increased temp. (up to 200°C): good ductility (impact strength): excellent fatigue strength amounts 80 to 110 N/mm² ( best available casting method, values for vibration durability up to 50*10 hoch 6 cycles [Woehler diagram]). To the comparable DIN-mark G-AlCu4TiMg, mat. No. 3.1371, acc. to DIN 1725-2 : 1986-02 applies: The alloy has a wide solidification interval, castability is more complicate. It is applied cold or warm hardened and suitable for casting parts of highest strength ( warm hardened) or highest ductility (cold hardened). Application: Wear resistant construction parts in engine, machine, vehicle and aircraft construction.
