High-end CoCr alloy for reliable and cost-effective restorations
Wirobond 280® is a proven BEGO alloy designed for metal-ceramic restorations in accordance with ISO 9693-1 and for composite veneering. Its formulation (chromium, molybdenum, tungsten) provides excellent corrosion resistance and high mechanical strength, even on long-span restorations.
Its optimized coefficient of thermal expansion helps reduce stresses during ceramic firing with many ceramics. The low thermal conductivity also contributes to clinical comfort while maintaining excellent framework stability.
Indications & benefits for dental laboratories
- Reliable ceramic bonding: promotes stable layering with strong adhesion on copings and frameworks.
- Easy handling: Vickers hardness around 280 HV10 (up to ~315 HV10) allows efficient finishing and polishing.
- Precise casting: very good castability, ideal for fine structures and detailed margins.
- Nickel-free / beryllium-free: improved comfort and safety in daily laboratory work.
- Biocompatible: formation of a stable passive layer, evaluated by an independent institute (biological certificate).
- High corrosion resistance: Co-Cr-Mo-W synergy ensures long-term stability of restorations.
Applications (fixed prosthetics)
- Copings and frameworks for metal-ceramic restorations (ISO 9693-1).
- CoCr frameworks for composite veneering.
- High-strength frameworks for short and long spans.
- Lab tip: ensure optimal ceramic adhesion with consistent surface preparation (degreasing + sandblasting/oxidation according to ceramic protocol).
Workshop instructions
- Follow BEGO recommendations for melting and casting according to your equipment.
- Use appropriate sprue design and feeding to maintain precision in fine areas.
- After casting: perform finishing and polishing (simplified due to optimized hardness).
- For ceramics: follow the ceramic manufacturer’s guidelines; extended cooling is generally not required.
