Chromium-Cobalt Alloy for Ceramics (1 kg) - Indensa

Chromium-Cobalt Alloy for Ceramics (1 kg)

Characteristics of the metal:

• Alexium W is a beryllium-free chromium-cobalt alloy, developed for fixed prostheses coated with dental ceramics.
• It offers high mechanical resistance and excellent thermal behavior, ideal for demanding laboratory work.
• It allows for smooth and glossy finishes, improving the final aesthetics of restorations.
• It has a high resistance to corrosion, which guarantees the clinical durability of the work.
• It can be used by mixing 50% new material with 50% already cast, without affecting the quality of the result.
• Recommended for ceramic metal structures such as crowns, bridges, and multiple restorations.
