- Top-rate alloy, tried and tested worldwide since 1972, with superior mechanical properties
- Universal alloy for clasp dentures
- Very high elongation after fracture means easy activation of the clasps
- Ideal for laser welding with Wiroweld due to reduced carbon content
- Biocompatible and corrosion-resistant due to the firmly passive layer
- All aspects of the ISO 22674 requirements were been greatly exceeded
This alloy is basically processed using the proven BEGO system. The system with WiroFine or Wiroplus® S investment and the Wirosil® duplicating flasks is advantageous.
WIRONIUM® plus cobalt-chrome alloy demonstrates that something which is “good” can still be improved upon. WIRONIUM® plus is the result of our research and development activities. This universal alloy was systematically further developed from proven WIRONIUM® and is equally suitable for fixed/removable restorations and clasp dentures.
We achieved the outstanding properties by using a special alloy technique in the continuous casting process and the addition of tantalum. The proof stress and ultimate strength were increased without significantly altering the superior elongation at rupture. A denture fabricated using WIRONIUM® plus has a high resistance to deformation, whereby clasps can be easily activated.
All aspects of the ISO 22674 requirements have been greatly exceeded.
WIRONIUM® plus is biocompatible and has no cytotoxic potential. The biocompatibility is certified by a neutral institute.
WIRONIUM® plus is ideal for laser-welding with Wiroweld due to its reduced carbon content.
This alloy is also basically processed using the proven BEGO system in exactly the same way as the other WIRONIUM® alloys. The system with WiroFine or Wiroplus® S investment and the Wirosil® duplicating flasks is advantageous. There is only a slight difference in the melting process and recognition of the casting point.
When the molten metal is uniformly light and moves slightly due to the pressure of the flame.
