Alloy dental material Starbond CoS

for dental restorationsbiocompatible

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 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 Composition: Co - 59% Cr - 25% W - 9.5% Mo - 3.5% Si - 1% C,Fe,Mn,N - <1% Technical properties: Proof stress (Rp 0.2) - 650MPa Ultimate tensile strength - 910MPa Elongation - 8% Elastic modulus - 200GPa Vickers hardness - 280 HV 10 Density - 8.8g/cm³ Melting range - 1305 - 1400°C Preheating temperature - 850 - 950°C Casting temperature - 1500 - 1550°C CTE (20-600°C) - 14.0 x 10⁻⁶K⁻¹ Laser weldable - Yes Type (DIN EN ISO 22674) - 5
