The noble alloy
tended to fail at the metal-cement interface and within the cement itself with predominantly adhesive failure.
Valve, Houston, a division of Fike Corporation, and a leading provider of high end alloy valves for erosive/corrosive services recently launched their new e-commerce enabled web site.
Valve, a division of the Fike Corporation, recently received their ISO 9001:1 994E certification from The American Petroleum Institute Quality Registrar (APIQR) for the design, manufacture, repair, and testing of valves, actuators, and accessories, as well as the surface hardening of metals under IAF Code 17.

Among the advantages of using noble alloys
is that they have a lower elastic modulus allowing the occlusal forces to transmit more efficiently to the remaining teeth.
 Barghi et al measured the fracture strength of repeatedly fired porcelain veneered to high noble and base metal alloy crowns and reported that multiple firings decreased the fracture strength in high noble alloys
but did not significantly affect base metal alloys.
The American Dental Association classifies dental casting alloys into three categories based on their noble metal content (noble alloys
have low corrosion in oral applications).
The strength and rigidity of titanium are comparable to those of other noble or high noble alloys
commonly used in dentistry [27, 28].
It is known that the casting process may increase the porosity of noble alloys
, particularly those containing palladium (Pd) in their composition.
