Wironit Extra-hard
Wironit® extra-hard, the ideal partial denture alloy for combination work
Due to its high proof strength and ultimate strength, this alloy is ideally suited for combination work.
Outstanding casting properties thanks to the special composition with silicon and carbon.
Very low thermal conductivity of the alloy emphasises the wearing comfort of the prosthesis.
Biocompatible and corrosion-resistant.
Type 5: Indicated for prosthetic restorations where parts thereof require a combination of high rigidity and strength, e.g. thin removable partial dentures, sections with thin cross-sections, clasps.
