The biocompatible CoCr-based ceramic alloy. An excellent solution for even the most graceful constructions.

Your benefits:

• Simple and quick processing and polishing
• Easy handling, similar to handling a high-precious alloy
• Oxide on full cast objects can be removed easily with a rubber polisher
• Low risk of overheating, the ingots become visibly liquid at the melting point
• Easy to grind, ideal for telescopic restorations
• Smooth and homogeneous surfaces after taking out of the mold
• Light oxide = more aesthetic color of the facing
• Ideal for laser welding

Easy processing, excellent grinding behavior by means of an optimal hardness

• Optimal CTE value, similar to the CTE of a classic ceramic alloy
• Biocompatible, free of nickel and beryllium
• High corrosion resistance

Physical properties:

• Type: 4 (EN ISO 22674)
• Composition (%): Co 61.1/Cr 27.8/W 8.5/Si 1.7
• Melting interval (°C): 1320-1420
• Casting temperature (°C): 1470
• CTE 25 – 600 °C 14.1 x  10^-6 K^-1
• Vickers hardness (HV 10): 280

Benefits:

• Extremely hard
• High elongation at break
• Easily removed oxide
• Excellent to polish
• Extremely bright sheen after polishing
• For delicate model casting
• Suitable for large and also delicate construction

Physical attributes

• Hardness: HV 398
• Elongation at break: 6%
• Tensile strength: 980 µPa
• Specific weight: 8.3 g/cm²
• Melting range: 1368-1385 °C

Both alloys contain &lt, 0.5% carbon. They are suitable for lasers and will not become brittle (heat cracks). Both alloys have been tried and tested for more than 25 years. They are biologically safe and bio-compatible. Naturally, neither alloy contains nickel or beryllium or any other contentious ingredients.
