Description

The Chrome Cobalt (CoCr) Open System Disc is designed for dental laboratories using open-architecture CAD/CAM milling systems. Manufactured to meet EN ISO 22674 for non-precious alloys and ISO 9693-1 for porcelain-fused-to-metal restorations, this disc is completely free of nickel and beryllium, making it a safe, biocompatible choice for patients with metal sensitivities. Its low-oxide composition allows for excellent polishing results, while the ideal coefficient of thermal expansion ensures compatibility with a wide range of ceramic veneering materials. Available in a 98.5mm diameter to fit standard open-system mills, this disc is ideal for crown and bridge frameworks requiring strength, precision, and long-term biocompatibility.
