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
