$\huge\underline\mathfrak\color{blue}Answer$

A metal that resists chemical action, does not corrode, and is not easily attacked by acids .. Ex -gold, silver, or platinum.

Noble metals used for dental castings continue to consist of alloys of gold, palladium, and silver (not a noble metal), with smaller amounts of iridium, ruthenium, and platinum. The majority are used as a backing for ceramic baking, with the rest used as inlays, onlays, and unveneered crowns.
