In plain English: Metallic means having the shiny, hard look and feel of metal.

Usage: Use metallic to describe objects that resemble shiny metals in appearance or sound rather than being made of actual metal. This adjective often distinguishes the quality of a material from its specific composition when discussing texture or resonance.
The word metallic comes from the Latin metallum, meaning "metal," which itself was borrowed from Ancient Greek. It entered English as a standard adjective formed by adding the suffix -ic to the root word metal.
