Wirobond® 280
The non-precious premium alloy for more than 10 years
- Wirobond® 280 is setting standards in the non-precious metaltoceramic alloy segment because of a Vickers hardness of 280 HV10, it can be finished to a particularly high standard
- Extremely corrosion resistant thanks to the optimal interaction of the indispensable elements chrome and molybdenum
- Very good melting and casting properties
- No prolonged cooling necessary*, even with large spans
- Secure bonding with ceramics
- High strength irrespective of the span size, and therefore a wide range of indications
- Reliable processing in accordance with the proven BEGO system
- Biocompatible and corrosion-resistant
