When aluminium alloys are cast, there are many potential sources of defects which can harm the quality of the casting such as shrinkage defects, gas porosity and oxide inclusions. Pressure die casting is the most commonly used casting process for aluminium as well as magnesium alloy castings. Their main advantage is their light weight. The melting of copper and copper-based alloys also presents special problems. Molten copper dissolves both oxygen and hydrogen and on solidification, these can cause porosity in the casting.
