NPM-Bonding Alloy / CoCr based
Starbond Easy
CoCrW bonding alloy for conventional, high-fusing (low expansion) ceramics. Free of nickel, lead, beryllium and cadmium. Type 4 pursuant to DIN EN ISO 22674.
- High degree of purity
- Biocompatible and extremly corrosion resistant
Advantages for Dental Technicians:
- System-free working due to very good alloy properties
- Pleasant polishing properties and finishing due to low hardness of 285 HV10
- A CTE of 14.4 enables 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
