While carbon can assume certain forms to give it metal-like properties (namely, being able to conduct electricity under specific conditions), the next item down on the periodic table, sulfur, does not have any such properties. Under normal conditions it exists as a yellow powder or as a brown liquid when heated, among other forms, and doesn't have any metal properties like being malleable (i.e. you can hammer it into a shape), being able to conduct heat and electricity easily, and so on.
However, sulfur is useful as a nonmetal, and the most common way I used it was in the form of sulfuric acid. You can form a wide variety of useful compounds from sulphur, and scientists do use sulfur-containing materials wherever it's useful.
