Phase Diagram of Al-Ca-Mg-Si System and Its Appliion …

Regardless of the Ca and Si content, the solidifiion of the aluminum-magnesium alloys ends with the following nonvariant eutectic reaction: L → (Al) + Al4Ca + Mg2Si + Al3Mg2. With respect to the temperature and composition of the liquid phase, this reaction is close to the eutectic reaction in the Al-Mg binary system.

How fluxing purifies aluminum

In this processing ensures optimum degassing, removing oxides and receiving slag with low aluminum content (picture 7). Without applying flux such rotary treatment is not as effective for the removal of oxides and, Moreover, leads to the formation of slag with a high content of aluminum (drawings 8 and 9).
