The alloy represented by the diagram is diamond cubic.
This alloy is very hard and has a high melting point because of the strong covalent bonding between the atoms. In a diamond cubic structure, each atom is strongly bonded to four other atoms in a tetrahedral arrangement. Covalent bonds are very strong, requiring a large amount of energy to break. This strong bonding results in a high hardness and a high melting point.
