Wirobond® 280

Non-precious metal premium alloy for metal-ceramic or composite veneering - nickel-free, beryllium-free

  • The new standard
  • Extremely corrosion resistant due to the optimal interaction of the essential elements chromium and molybdenum
  • Biocompatibility certified by neutral institute
  • Low thermal conductibility
  • High strength with any practical length of span
  • Reduced hardness of 280 VH10 ensures easy preparation
  • No long-term cooling required
  • Reliable bonding with ceramic
  • Reliable technique based on the proven BEGO system
