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
