Starbond CoS

Starbond CoS

CoCrWMo bonding alloy for conventional, high-fusing (low expansion) ceramics. Free of nickel, lead, beryllium and cadmium. Type 5 pursuant to DIN EN ISO 22674.

• High degree of purity
• Biocompatible and extremly corrosion resistant

Advantages for Dental Technicians:

• Wide range of indications
• System-free working due to very good alloy properties
• Pleasant polishing properties and easy finishing due to low hardness of 280 HV10
• A CTE of 14.0 enables flexibility in ceramic selection and safe veneering
• No cooling phase required, depending on the ceramics
• 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
