Wiron® light

The non-precious alloy for metal-to-ceramic work, with light oxide – beryllium-free

  • Simple casting, easy finishing, reliable working
  • The outstanding melting properties of the alloy ensure reliable filling of the mould
  • The oxide of Wiron® light is considerably lighter in colour in comparison to conventional NiCr alloys and can be removed very quickly and easily
  • The reduced preheating temperature of 800°C means that a very smooth surface of the cast object is achieved
  • Normal cooling with many of the ceramics – for time-saving, economical veneering
  • The favourable CTE value permits reliable ceramic veneering
  • Biocompatible and highly corrosion-resistant thanks to a firmly adhering passive layer
