Wirobond® 280 250 g

• Wirobond^® 280 is setting standards in the non-precious metal-to-ceramic alloy segment because of a Vickers hardness of 280 HV10, it can be finished to a particularly high standard

• Extremely corrosion resistant thanks to the optimal interaction of the indispensable elements chrome and molybdenum

• Very good melting and casting properties

• No prolonged cooling necessary*, even with large spans

• Secure bonding with ceramics

• High strength irrespective of the span size, and therefore a wide range of indications

• Reliable processing in accordance with the proven BEGO system

• Biocompatible and corrosion-resistant
