Carbon-free casting alloy for clasp dentures and partial denture bases, available in two stiffness degrees: hard (l) and extra-hard (fh). Since no carbon is contained, crack-building carbide precipitation during laser welding is prevented. Niobium which is known to build a fine-grain structure ensures good polishability and a rich shade.
 | High stability/stiffness, nevertheless easy to process |
| No clasp fractures, even if activated several times |
| Enough design and safety reserves thanks to the high strength values |
| Dense, homogeneous surface, easy to polish, rich shade due to niobium |
