| 1) Remark: Material EN-MCMgAl4Si, trade name AS 41 is produced as diecasting. It is a an alloy for special applications, it shows favorable creep behaviour up to 150°C, e.g. for long-term thermal loaded castings in combustion engines. The material allows for economical large-scale production of quality castings. The alloy is excellent machinable (regulations of the professional association have to be considered), shows high damping power and no embrittlement tendency at low temperatures. High oxidation tendency of the melted magnesium and of the Mg-chipping requires special measures when melting, casting, trimming and welding. Application in engine, machine and apparatus engineering. Magnesium and its alloys show the easiest machinability of all known construction metals. Casting for special application ranges is liable for licence. |
