Wirobond® C

Cobalt-chrome metal-to-ceramic alloy

  • Nickel- and beryllium-free
  • Simple processing thanks to reliable casting time recognition
  • Carbon-free composition – particularly well suited for laser welding
  • The element cerium ensures high bond strength with the ceramic, minimising the risk of subsequent flaking or chipping
  • Low thermal conductivity – protects the pulp and ensures high wearing comfort for the patient
  • Biocompatible and corrosion-resistant thanks to a firmly-adhering passive layer
