Wironium Extra-hard
WIRONIUM® extra-hard, Cobalt-chrome partial denture alloy
Ideal when an alloy with higher strength is required.
Very slender designs possible – for high patient comfort.
Reduced carbon content – particularly well suited for laser welding.
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.
