Description

Available in 250 grams or 1000 grams.

Wirobond® 280 is setting new standards in the non-precious metal-to-ceramic alloy segment because, with 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
  • Biocompatibility examined by an independent institute and confirmed with a bio certificate
