The broad classification of metals encompasses several distinct chemical and industrial categories tailored to specific structural applications. Ten primary types and categories of metals include transition metals (like iron and copper), alkali metals (such as sodium and lithium), alkaline earth metals (including magnesium and calcium), precious metals (like gold and silver), post-transition metals (such as aluminum and tin), refractory metals (like tungsten), rare earth metals, ferrous metals, non-ferrous metals, and heavy industrial metal alloys like structural steel and brass.
