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
