Hocera CoCr Metal Blank Disc
High-Strength Cobalt-Chrome Discs for Precision CAD/CAM Restorations
Introduction
The Hocera CoCr Metal Blank Disc is a premium cobalt-chrome CAD/CAM solution designed for high-precision fabrication of crowns, bridges, implant bars, and porcelain-fused-to-metal (PFM) restorations. Engineered with a medical-grade CoCr alloy formula, these discs provide exceptional corrosion resistance, stable porcelain bonding, and long-term intraoral durability.
With an optimized composition—Co 61%, Cr 26%, Mo 5%, W 6.5%—Hocera CoCr blanks deliver a tensile strength ≥560 MPa, elongation of 7%, and a uniform micro-grain matrix ideal for detailed milling. Manufactured with strict density controls, every disc offers a clean internal structure that supports smooth machining, precise marginal integrity, and superior ceramic layering.
Available in 98 mm diameter and 10–25 mm thickness, these discs seamlessly integrate into open CAD/CAM workflows, supporting systems from Roland、VHF、Amann Girrbach、Sirona 等。
Strong milling performance. Clean surface quality. Excellent porcelain fusion. Hocera CoCr delivers consistent results for the modern dental laboratory.
Key Features
1. Premium CoCr Alloy Composition
Co 61%, Cr 26%, Mo 5%, W 6.5%
Provides superior tensile strength, corrosion resistance, and excellent compatibility with ceramic powders.
2. High Mechanical Strength (≥560 MPa)
