Product catalog summary
Overview: The document provides detailed information on non-precious metal milling discs used in dental technology, specifically focusing on titanium and CoCr (Cobalt-Chromium) alloys. These discs are used for manufacturing dental structures such as crowns, bridges, and implant-supported superstructures.
1. Titanium Milling Discs:
  • STARBOND TI4 DISC: Made of pure titanium (Grade 4) with high oxygen content. Composition: Ti >99%, N, C, H, Fe, O <1%. Advantages include excellent ceramic bonding, biocompatibility, corrosion resistance, and low thermal conductivity.
  • STARBOND TI5 DISC: Composed of grade 5 "ELI" titanium alloy TiAl6V4. Composition: Ti 89.4%, Al 6.2%, V 4%, N, C, H, Fe, O <0.4%. Offers ideal mechanical properties, excellent ceramic bonding, and is suitable for implant-supported restorations.
2. CoCr Milling Discs:
  • STARBOND EASY DISC: CoCrW alloy, free of nickel, beryllium, cadmium, and lead. Composition: Co 61%, Cr 27.5%, W 8.5%, Si 1.6%, C, Mn, Fe <1%. Features include medium hardness, excellent metal-ceramic bonding, and suitability for dry and wet milling.
  • MOGUCERA C DISC: CoCrMo alloy, free of harmful elements. Composition: Co 65%, Cr 28%, Mo 5%, C, Si, Nb, Mn, Fe <1%. Known for excellent machinability and easy polishing.
  • STARBOND COS DISC BASIC: CoCrWMo alloy, designed for industrial milling units. Composition: Co 59%, Cr 25%, W 9.5%, Mo 3.5%, Si 1%, C, Fe, Mn, N <1%. Offers flexibility in ceramic selection and excellent bonding.
  • FUSIONIS DISC: CoCrMo alloy for fixed and removable dentures. Composition: Co 63%, Cr 29%, Mo 5%, C, Si, Nb, Mn, Fe <1%. Notable for its machinability and validated process.
3. Technical Properties:
  • Titanium Discs: Proof stress ranges from 504 to 837 MPa, density around 4.4-4.5 g/cm³, ultimate tensile strength from 599 to 921 MPa, and Vickers hardness >200 HV5/30.
  • CoCr Discs: Proof stress ranges from 413 to 441 MPa, density around 8.3-8.8 g/cm³, ultimate tensile strength from 597 to 663 MPa, and Vickers hardness around 281-290 HV 10.
4. Product Variants: The document lists various dimensions and references for each type of disc, indicating availability with or without edge.
Conclusion: These milling discs offer dental technicians a range of options for creating durable, biocompatible, and corrosion-resistant dental structures, with specific advantages tailored to different dental applications.
