Casting is the operation that consists in extracting the molten metal from the melting apparatus and in introducing it into the molds. It requires constant focus and significant know-how. Cast irons are alloys. At GHM, they differ from other alloys by their excellent flowability. Cast iron has a melting temperature ranging from 2 075° F to 2 553° F (1,135 ° C to 1,400 ° C), essentially depending on the percentage of carbon and silicon it contains. When it is molten, its maximum carbon content can reach 6,7 %. The GHM factory also produces work made from cast aluminum and bronze alloys.
