Wironit

The classical partial denture alloy for clasp prothesis.

Product Photo

Successful all over the world since 1953. Characteristics allow for clasp stability and user friendliness. A Vickers hardness of 330 results in a high luster polish while the yield strength of 6.2 allows flexibility for chair side adjustments. Wironit Extra Hard is great for lower cases and milled work where more strength is needed.
