Wirobond 280
Non-precious metal premium alloy for metal-ceramic or composite veneering - nickel-free, beryllium-free
- The new standard
- Extremely corrosion resistant due to the optimal interaction of the essential elements chromium and molybdenum
- Biocompatibility certified
- Low thermal conductibility
- High strength with any practical length of span
- Reduced hardness of 280 HV10 ensures easy preparation
- No long-term cooling required
- Reliable bonding with ceramic
- Reliable technique based on the proven BEGO system
