Wirobond^® 280

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
