Nu Alloy dp® is a dispersed-phase, high-copper-content dental alloy with no zinc content. Dispersed-phase: A mixture of lathe-cut irregular particles and atomized spherical particles. High-copper-content: >12%. Nu Alloy® dp is a single composition alloy with absolute homogeneity of its particles. Thanks to its optimal chemical composition (45%Ag, 31%Sn, and 24%Cu) and its high copper content, the gamma-2 phase is eliminated from the alloy microstructure. As a result of this, fragility and instability problems in corrosive environments decrease. Its morphology is composed of atomized and lathe-cut particles which results in a fast amalgamation with its optimal 50% mercury content (Mercury-to-alloy ratio: 1:1) and improves the alloy’s physical and mechanical properties. This alloy has a high resistance to marginal fractures, excellent adaptation and marginal sealing, thanks to the homogeneity of its particles. Fine surface finish originated in the granulometry of its spherical and prismatic particles.
