Wirobond 280

Wirobond® 280 – The non-precious premium alloy for more than 10 years

  • Wirobond® 280 is setting standards in the non-precious metal-to-ceramic 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
  • Type 5: Indicated for prosthetic restorations where parts thereof require a combination of high rigidity and strength, e.g. thin removable partial dentures, sections with thin cross-sections, clasps.
