Product Overview

Our Nickel based sintered dental alloy, Marranium FI, stands out with its excellent biocompatibility, which has been clinically tested and proven on the market. It demonstrates superior mechanical properties, exceeding even those of some cobalt-base alloys.

You can easily combine Marranium FI with almost any ceramic mass available on the market, thanks to its optimal thermal coefficient of expansion. In addition, you can add exactness to the shape of surface of your metal denture bases by using Marranium FI, as it features supreme castability.
