Description

•Wirobond® 280 is setting standards in the non-precious bonding alloy segment. The low Vickers hardness of 280 HV10 and a very good spanability facilitate processing

• High corrosion resistant thanks to the interaction of the indispensable elements chrome, tungsten and molybdenum

• Very good melting and casting properties

• No prolonged cooling necessary*, even with large spans, due to optimised coefficient of thermal expansion

• Secure bonding with ceramics

• High strength of the alloy for safe processing even of the large span size of bridges

• Reliable processing in accordance with the proven BEGO system

• Biocompatible and corrosion-resistant
