Price (incl. VAT) €262.95
A historic, proven CoCr alloy since 1953, specifically developed for
conventional clasp-retained removable partial dentures, delivering strength,
dimensional stability and reliable clasp activation.
✔︎ Clasp-retained partial dentures
✔︎ High mechanical strength
✔︎ Reliable clasp activation
✔︎ Excellent castability
✔︎ Biocompatible
✔︎ Corrosion-resistant
A benchmark CoCr alloy for stable, long-lasting partial dentures
Wironit® is a BEGO cobalt-chromium alloy trusted for more than 70 years for manufacturing clasp-retained removable partial dentures. Its mechanical properties far exceed national and international standards, ensuring reliable, strong and durable restorations.
Its high ductility enables frequent, safe clasp activation while maintaining excellent dimensional stability during mastication. The dense, smooth surface helps reduce plaque build-up and protects the restoration from deposits.
Clinical and technical benefits
- High strength: long-term stability of shape and function.
- Optimised ductility: precise, repeatable clasp activation.
- Dense, smooth surface: reduced deposits and plaque accumulation.
- Excellent visibility of the casting point for safer handling.
- Reliable casting by induction or flame casting.
- Biocompatible and corrosion-resistant.
Applications
- Removable partial dentures with conventional clasps.
- Stellite frameworks requiring strength and ductility.
- Partial restorations exposed to high mechanical loads.
Laboratory workflow
- Castable on induction casting units (e.g. Fornax® T, Nautilus® CC plus) or other brands.
- Compatible with flame casting.
- Preheating temperature: 950 to 1050 °C.
- Casting temperature: ≈ 1420 °C.
