This category represents the “gold standard” of dental alloys, and the one by which all other types are compared.
The composition of a high-noble must include over 60% precious metal (gold, platinum, and/or palladium), of which over 40% is gold.
Alloys in this group must have a composition that’s over 25% precious metal (gold, platinum, and/or palladium).
These alloys contain less than 25% precious metal. A large portion of their content may be nickel, chromium or beryllium. (Some people are allergic to these metals, see above.)
