The third group of Mg–Al–Zn with increased Zn content, represented by the AM–lite, benefits from the influence of Zn. The AM–lite does not contain rare earth or other exotic elements [26]. 02 g/cm3, the alloy is half way between typical Mg based alloys and Al. The AM–lite has a better die castability than AZ91D and a much better surface finish. 5 Alloys 35 400 Mg12Al1Zn5Sn 350 Mg12Al3Zn5Sn Flow length, mm 300 Mg9Al1Zn 250 200 150 100 50 0 530 550 570 590 610 630 o Melt temperature, C Fig. 21 The flow length of Mg12Al3Zn5Sn and Mg12Al1Zn5Sn alloys compared to Mg9Al1Zn.

Depending on the casting hardware, the amount of scrap generated in the foundry reaches typically 50% to 70%. Type II represents the oil-contaminated scrap and type III includes dross (oxide formed on the top surface of the melt) and sludge (contaminant particles accumulated at the bottom of a crucible or furnace). Type IV covers chips and fines. The broader classifications also exist, where scrap is divided into up to 9 classes. At present only the high quality scrap can easily be recycled into high purity alloys.

9 The experimental setup for direct magnesium production from magnesium oxide using Solid Oxide Membrane [4] instrument’s top is used to supply MgO to the melt. The process is still in laboratory stage and the system can produce up to 1 kg of magnesium per day. 4), the reaction is favored at high temperatures, typically above 1700 °C (Fig. 10). While operating at lower temperatures the product gas should be diluted with an inert gas. 1 1300 1400 1500 1600 1700 1800 1900 o Temperature, C Fig. 4) [5] The major technical challenge is preventing the reverse reaction, achieved by rapid quenching of the vapor and dissolving magnesium in a metal solvent [5].
