The non-precious alloy for metal-to-ceramic work or acrylic veneering - free of beryllium. Optimised for laser welding Biocompatible, proven worldwide and reliable. Extremely high resistance to corrosion: no cytotoxic potential in cell culture test. Biocompatibility certified by neutral institutes. Low thermal conductivity. High modulus of elasticity. Great strength with any acceptable span. Easy finishing thanks to low hardness of 180 HV10. Long cooling time not required: low coefficient of expansion. Reliable metal-to-ceramic bond. High heat resistance: dimensional stability during firing and soldering. Reliable processing according to proven Wiron system.
