Answer:
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.
Explanation:
Besides resistance to heat and oxidation, gold is malleable (able to be flattened into sheets) and ductile (able to be drawn into wire).
Platinum's color and durability makes it an attractive choice for jewelry. Platinum is sometimes alloyed with gold to make "white gold," which is used in dental work as well as jewelry.
The six transition elements in Group VIII of the periodic table are known collectively as the platinum metals (ruthenium, rhodium, palladium, osmium, iridium and platinum).
