NPM-Bonding Alloys / NiCr Basis
Starbond Ni
NiCr-bonding alloy for conventional, high-fusing (low expansion) ceramics. Free of beryllium, cadmium and lead. Type 3 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 easy finishing due to low hardness of 200 HV10
- Flexibilität bei der Keramikauswahl und sicheres Verblenden
- Excellent metal-ceramic bonding, even without bonder
- Optimal conditions for laser welding
- Application flexibility and easy melting, no sparking
- An oxidation firing can be omitted
