SYSTEM SIN is a nickel- and beryllium free alloy in powder form on cobalt-chrome base.
SYSTEN SIN is suitable for crowns and bridges for the ceramic veneering as well as for the removable denture in the laser-melting process.
One of the remarkable features of SYSTEM SIN is the high corrosion resistance.
