Amalgam Filling Materials


MARVALLOY is a high copper dental silver alloy consisting of a constant ratio of spherical and lathe cut particles. As a result of this, great handling characteristics are obtained. Its high early strength together with its low static creep value lowers the risk of marginal fracture and assures long-lasting marginal integrity. It does not contain zinc thus eliminating problems due to moisture and avoids the corrosive gamma-2 (γ-2) phase. Tin dissolves in mercury and is preferentially bound to copper thus forming Cu6Sn5 which inhibits formation of the corrosive gamma -2 phase (Sn8Hg).
