In English grammar, "metal" is generally considered an uncountable noun. Uncountable nouns refer to substances or concepts that cannot be counted as individual units. In the case of "metal," it is used to describe a material or element in a general sense, rather than specific instances of metal objects. However, in certain contexts, "metal" can be used as a countable noun when referring to specific types or forms of metal, such as "gold," "silver," or "aluminum."
