What is a material that is made from a raw material but is not a consumer product?

A common example of a material made from a raw material but not a consumer product is steel. Steel is produced from iron ore, which is mined, processed, and then alloyed with carbon and other elements. While steel itself is not a consumer product, it serves as a fundamental material used in various industries for constructing buildings, bridges, and machinery. Its applications are integral to infrastructure and manufacturing, rather than direct consumer use.
