Metal dental material W-5

ceramicalloyporcelain

W-5 is a classical, reduced-gold ceramic alloy. The good casting characteristics and the high heat resistance allow for the production ceramic veneered to metal frameworks and implant-supported superstructures of high accuracy. Indications* Onlays, ¾ crowns, crowns Telescope crowns, conus crowns Bridges Wide-span bridges Cast posts / cores, bars, attachments Implant-supported superstructures Partial dentures Technical Data Composition (%): - Au 52.2 | Pd 26.0 | Ag 17.1 | Sn 2.7 | Pt <1.0, In <1.0, Ir <1.0, Re <1.0, Li <1.0 ISO - 22674:2016 ADA Class: - High Noble Type / Color: - 4 / White Density (g/cm³) - 13.8 Melting Range (Solidus/Liquidus): - 1185 - 1285 °C Elastic Modulus (GPa): - 130 - Porcelain Fired Hardened Vickers Hardness: - 215 255 Tensile Strength (MPa): - 715 745 0.2% Proof Stress (MPa): - 475 520 Elongation (%): - 15 12 Advantages Light oxide Good melting and flow characteristics High heat resistance Compatible with conventional metal-ceramics (e.g. IPS Style) Tested biocompatibility
