  • Non-precious alloy and use of same
    Publication number: 20010012491
    Abstract: What is proposed is a non-precious alloy with a cobalt-chrome or nickel-chrome base containing 30-70% nickel and/or cobalt, 20-35% chrome and 3-25%, in particular 12-15% manganese and/or iron. With such an alloy as casting material, it is possible to make dental products such as crowns, bridges, inlays and the like that can be ceramically veneered without problems arising as a result of different coefficients of thermal expansion.
