Wironit LA

Wironit® LA – Specially developed for laser welding

  • Wironit® LA – wide range of indications for reliable application in the partial denture and combination technique.
  • Controlled carbon content and the addition of tantalum ensure excellent laser welding properties even in extreme cases.
  • Low thermal conductivity means high wearing comfort for the patient.
  • Thanks to the high elongation of fracture, clasps can be activated without any problem.
  • 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.
