Description

Material EN AC-Al Mg9 is produced as diecast. It shows the following casting characteristics and properties: plasticity: acceptable heat crack resistance: insufficient pressure tightness: insufficient workability (after heat-treatment): excellent corrosion resistance: excellent decorative anodic oxidation: good weldability: acceptable polishability: excellent strength at room temperature: acceptable strength at increased temp. (up to 200°C): good ductility (impact strength): acceptable fatigue strength amounts 60 to 90 N/mm² ( best available casting method, values for vibration durability up to 50*10 hoch 6 cycles [Woehler diagram]). Diecast weldability depends on the embedded gas amount and is mostly insufficient. For certain cast methods are achievable good to acceptable values. To the comparable DIN-mark GD-AlMg9, mat. No. 3.3292, acc. to DIN 1725-2 : 1986-02 applies: The alloy is well brightenable, suitable for technical and anodic oxidization of undecorative appearance. Machinability is excellent, welding is not applied. Suitable for parts of high demands to corrosion resistance and surface appearance, e.g. optical industry, business machines and household appliances. The material is hard anodizable. Application: household and business appliances, optical devices, fittings, decoration, components for food industry
