Wironium Extra-hard

WIRONIUM® extra-hard, Cobalt-chrome partial denture alloy

  • Ideal when an alloy with higher strength is required.

  • Very slender designs possible – for high patient comfort.

  • Reduced carbon content – particularly well suited for laser welding.

  • Biocompatible and corrosion-resistant.

  • Type 5: Indicated for prosthetic restorations where parts thereof require a combination of high rigidity and strength, e.g. thin removable partial dentures, sections with thin cross-sections, clasps.
