Wiron 99

Non-precious alloy for metal-to-ceramic work or acrylic veneering - Beryllium Free -

Produktfoto
  • Extremely high resistance to corrosion
  • Biocompatibility certified
  • Low thermal conductivity.
  • High modulus of elasticity.
  • Great strength for long span bridges
  • Easy finishing thanks to low hardness of 180.
  • Long cooling time not required: low coefficient of expansion.
  • Reliable metal-to-ceramic bond.High bonding strength to ceramics
  • High heat resistance: dimensional stability during firing and soldering.
