Abstract (en)
[origin: WO2008020763A1] A process for casting a magnesium alloy consisting of 10,00 - 1300 % by weight of aluminium, 0,00 - 10.00 % by weight of zinc, and 5.00 - 13.00 % by weight of aluminium, 10.00 - 22.00 % by weight of zinc, also containing 0.10 - 0.5 % by weight of manganese, and the balance being magnesium and unavoidable impurities, the total impurity level being below 0. % by weight, wherein the alloy is cast in a die in which the temperature is controlled in the range of 150-340 °C, the die is filled in a time which expressed in milliseconds is equal to the product of a number between 2 and 300 multiplied by the average part thickness expressed in millimetre, the static metal pressures being maintained during casting between 20-70 MPa and may subsequently be intensified up to 180 MPa.
