Aluminium of 99.999% purity is immune, but alumililum of 99.8%or 99.5% purity and the Al-Si alloy are attacked by molten sodium at 350 - 500℃. The corrosion product formed on the surface of the materials is identified as the AlNaSi compound.This suggests that sodium attack of both aluminium and Al-12%Si alloy is the result of a reaction between sodium and the silicon contained in the aluminium.
