Which of the following materials is not suitable to be cast by a hot chamber die casting process?

Which of the following materials is not suitable to be cast by a hot chamber die casting process? Correct Answer Aluminium

The hot chamber die casting process is basically used for the low melting temperature alloys. But, for material such as aluminum, its high melting temperature makes it difficult to cast by hot chamber die casting process, because continuous contact of gooseneck with the molten metal can destroy the gooseneck material.
