Description
Cobalt Chrome Dental Disc
Cobalt chrome dental milling disc is nickel and beryllium-free.
It has excellent metal-porcelain bonding properties. The disc is also lasering weldable.
CAD-CAM Cobalt chrome dental milling disc in the laboratory is purposed to fabricate prosthesis of crowns, bridges, implant-supported superstructures, abutments, etc.
Main Features
1. Biocompatibility and high corrosion resistance thanks to firmly adhering passive layer.
2. Biocompatibility contact with human being bone
3. Hemolysis Ratio: 0.66%
4. No acute systemic toxicity
5. Cytotoxicity shall not exceed Class I
6. No oral mucous membrane irritation
7. No delayed dermal contact sensitization
8. No chronic systemic toxicity
9. No genetic toxicity
10. The cobalt chrome milling discs have high corrosion resistance: -Test medium and conditions: Volume fraction of 1% HCI solution, the temperature is constant at 37 ℃, 72 hours total immersion corrosion test -Test results: in the solution after corrosion, residual solution of 1% HCL solution has no discoloration, cobalt chrome alloy quality unchanged before and after corrosion test.
11. Alloy PFM products have good thermal shock resistance.
