написано:

Porcelain-fused-to-metal dental crowns (PFM's) can be fabricated using any one of a number of different alloys for the underlying metal substrate. Dental alloys used to make PFM crowns are categorized as being "precious" ("high noble"), "semi-precious ("noble") or "non-precious" ("base" or "non-noble"), depending upon their composition. "Precious" alloys are so named because they contain a greater percentage of the metals gold, palladium and/or platinum.
