Metals are chemicals in a certain sense. They are manufactured from ores and purified by many of the same processes as those used in the manufacture of inorganics. However, if they are commercialized as alloys or in their pure form such as iron, lead, copper, or tungsten, they are considered products of the metallurgical not chemical industry.
