Abstract
1481762 Ni based alloy PFIZER Inc 21 May 1975 [24 Dec 1974] 21982/75 Heading C7A A nickel based alloy containing: Cr 10-22 Mo 0-7 Al 1À0-5À0 Si 0À5-2À0 Mn 0À01-0À2 with Ni balance plus impurities, has good castability and is strong, tough, resistant to tarnish, oxidation, corrosion and is compatible with a human oral environment and may be easily fused to procelain and is suitable for use in dental restorations. The coefficient of thermal expansion of the alloy may be matched to that of the porcelain by adjustment of the W, Mo, Al and Fe contents.
