Wiron 99
Wiron® 99 – Premium NiCr alloy for metal-to-ceramic work or composite veneering – beryllium-free
Worldwide proven reliability in use since 1988.
Secure metal-ceramic bond, minimising the risk of subsequent flaking or chipping.
Low vickers hardness – for easy, fast finishing and polishing to a high lustre.
Simple casting time recognition – problem-free processing in all induction casting machines.
High modulus of elasticity for greater protection against deformations caused by masticatory forces.
High wearing comfort for patients thanks to the low thermal conductivity.
Biocompatible and highly corrosion-resistant thanks to a firmlyadhering passive layer.
Type 3: Indicated for fixed, multi-unit prosthetic restorations, e.g. bridgework.
