Wironium – Extra Hard 1 kg

Wironium® Extra Hard Cobalt chrome partial denture alloy

• Ideal when an alloy with higher strength and slightly lower ductile yield is required
• Very slender designs possible – for high patient comfort
• Reduced carbon content – particularly well suited for laser welding
• Biocompatible and corrosion-resistant – biocompatibility verified by an independent institute
