Wironit® LA Partial denture alloy 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 ductile yield of 8%, clasps can be activated without any problem
- Biocompatible and corrosion-resistant – biocompatibility verified by an independent institute
Wironit® LA: During wax-up, the casting funnel former must be positioned 10 mm above the highest point of the wax-up, to avoid the risk of defects in the cast object.
