Metal dental material Academy Gold

ceramicalloycomposite

Academy Gold is a high-precious, palladium-free casting alloy with an intensive golden yellow colour. The fine metal structure gives this alloy a high degree of tensile strength, which makes it ideal for inlays and onlays. Indications* Inlays Onlays, 3/4 crowns, crowns Technical Data Composition (%): - Au 77.2 | Ag 12.7 | Cu 8.5 | Pt <1.0, In <1.0, Ir<1.0, Zn <1.0, Ta <1.0 ISO - 22674:2016 ADA Class - High Noble Type / Color - 2 / Rich Yellow Density (g/cm³) - 15.9 Melting Range (Solidus/Liquidus): - 900 - 940 °C Elastic Modulus (GPa): - 88 - As Cast Softened Hardened Vickers Hardness: - 125 120 185 Tensile Strength (MPa): - 405 390 500 0.2% Proof Stress (MPa): - 240 225 335 Elongation (%): - 45 48 48 Advantages Pd-free Esthetic golden yellow colour Excellent marginal adaptation, also after tempering Excellent casting and processing properties Veneering with laboratory composites (e.g. SR Nexco) Tested biocompatibility Processing Data Investment Material: - Phosphate-bonded / Gypsum-bonded Preheating / Burn- out Temperature: - 650 - 760 °C Crucible - Carbon crucible / Ceramic crucible Casting Temperature: - 1000 - 1050 °C Recommended Lab Composite: - SR Nexco Laser Welding Wire: - Laser C&B Yellow
