Wironit Extra Hard 1 Kg

Wironit® Extra Hard The ideal partial denture alloy for combination work

• Due to its high elongation limit and tensile 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 – biocompatibility verified by an independent institute
