Wironium

WIRONIUM® Cobalt-chrome partial denture alloy

  • Top-quality alloy, proven worldwide since 1972 – ideally suited for conventional clasp partial dentures.

  • Excellent flow properties – simple processing.

  • Particularly suitable for laser welding with Wiroweld welding wire thanks to the reduced carbon content.

  • 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.
