SPECIAL ORDER or LOW STOCK HELD
Heraenium NA ‐ Nickel chromium base bonding alloy for use with classic porcelains.
Our Heraenium cobalt-chrome alloys are the result of intensive research.
The precious-metal-free alloys are economical alternatives that offer top quality. Heraenium alloys for crowns and bridges can be reliably veneered with ceramics from our HeraCeram lines and all other ceramics. HeraCeram NP-Primer ensures a secure bond between alloy and veneering ceramic even under critical oxidation conditions. It prevents uncontrolled formation of the oxide layer and dissolves it on the non-precious-metal surface as required to ensure optimum coating with ceramic. The basis for long-term aesthetics.
Benefits at a glance:
- good milling and polishing properties
- simple machining with low hardness
- free from beryllium and cadmium
- can be laser-welded and soldered
- very good corrosion resistance
NON PRECIOUS METAL ALLOYS FOR CROWN AND BRIDGEWORK
Heraenium NA
NiCr – non precious alloy
Nickel chromium bonding alloy for use with classic porcelains, in particular HeraCeram, and composites (Signum) acc. to EN ISO 9693 and 22674
Heraenium NA is a reliable nickelchromium based non precious metalalloy, primarily indicated for fabricating frameworks for metal-ceramics and specifically for use with classic porcelains such as HeraCeram. The framework can also be veneered with composites
Heraenium NA is free of beryllium and cadmium, exhibits good trimmed due to its minimal hardness.Especially when veneered with HeraCeram porcelain, aesthetic, high grade and dependable prosthetic restorations can be fabricated.
Kulzer Heravest Onyx and Molda vest exact investments are recommended for casting this alloy as they produce precisely fitting, smooth, fissure free castings.
