NPM-Bonding Alloys / CoCr based

Starbond LFC

CoCrFe bonding alloy for low fusion ceramics. Free of nickel, beryllium, cadmium and lead. Type 4 pursuant to DIN EN ISO 22674.
  • High degree of purity
  • Biocompatible and extremly corrosion resistant

Vorteile für den Zahntechniker:

  • System-free working due to very good alloy properties
  • Pleasant polishing properties and easy finishing due to low hardness of 315 HV10
  • Flexibility in ceramic selection and safe veneering
  • Excellent metal-ceramic bonding, even without bonder
  • An oxidation firing can be omitted
  • Optimal conditions for laser welding
  • Application flexibility and easy melting, no sparking 
  • Wide spectrum of indications including long span bridges
