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 color 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 favorable CTE value permits reliable ceramic veneering
  • Biocompatible and highly corrosion-resistant thanks to a firmly-adhering passive layer

Wiron® light: To ensure that the ceramic bonds firmly to the metal, it is essential that the bonding surface is trimmed with sharp tungsten carbide cutters. The manufacturer’s recommended speed must be adhered to. Following this, the surface must be sandblasted with an abrasive of predefined grit size, such as Korox® 250, at the recommended compressed air pressure of 3–4 bars. It is essential to clean the surface with a steam-cleaner, such as the Triton, or in boiling water.
