The document describes different types of materials including pure metals like copper and aluminum extracted from their ores, alloy metals like steel made from iron ore, natural materials like wood, manufactured boards, and synthetic materials like thermoplastics, thermosettings, and elastomers made from polymers derived from petrol and coal. These materials are then used to make various objects and structures.
