Κράματα Μη Πολύτιμων Μετάλλων

Κράματα Μη Πολύτιμων Μετάλλων

Τα χρωμιο-κοβαλτιούχα κράματα Heranium είναι το αποτέλεσμα εντατικών ερευνών.

Τα κράματα χωρίς πολύτιμα μέταλλα είναι οικονομικότερες εναλλακτικές που προσφέρουν άψογη ποιότητα. Τα κράματα Heranium για στεφάνες και γέφυρες μπορούν να καλυφθούν αξιόπιστα με κεραμικά από τις σειρές μας HeraCeram, καθώς και με όλα τα άλλα κεραμικά. Το HeraCeram NP-Primer εξασφαλίζει έναν ισχυρό δεσμό μεταξύ του κράματος και του κεραμικού υλικού ακόμα και σε περιπτώσεις με κρίσιμα οριακή συμπεριφορά οξειδίων.

Αποτρέπει την δημιουργία ανεξέλεγκτου στρώματος οξειδίου και το διαλύει στην επιφάνεια που δεν εμπεριέχει πολύτιμα μέταλλα, όπως απαιτείται για να διασφαλιστεί η ιδανική επικάλυψη με το κεραμικό. Η βάση για μακροχρόνια αισθητική.

Πλεονεκτήματα με μια ματιά:
  • Καλό φρεζάρισμα και γυαλιστικές ικανότητες
  • Απλή κατεργασία με χαμηλή σκληρότητα
  • Χωρίς βηρύλλιο και κάδμιο
  • Μπορεί να συγκολληθεί με laser ή απλά
  • Πολύ ανθεκτικό στη διάβρωση

Heraenium P
CoCr-based non-precious metal alloys

Cobalt-chrome-based bonding alloy for conventional ceramics especially for HeraCeram acc. to EN ISO 9693-1 and 22674.
Heraenium P was specially designed for classic veneer ceramics like HeraCeram. Heraenium P is a reliable non-precious metal alloy for the manufacture of frameworks, beryllium-, cadmium- and lead-free, with high cobalt and chrome content for optimum processing with good corrosion resistance.
Aesthetic, high-quality and reliable prostheses can be manufactured, especially when used together with HeraCeram. Customers appreciate the good polishability. This non-precious metal alloy with low CTE from Kulzer GmbH is clinically proven, biocompatible and highly resistant to corrosion. It is compliant with all the requirements of EN ISO 9693 and EN ISO 22674.
For further processing of the alloy, Kulzer recommends the investment material Heravest Onyx, with which allows accurately fitting, smooth casting results to be obtained.
Advantages
  • Beryllium, cadmium and lead free
  • Wide range of indications
  • very good corrosion resistance
  • easily polished
  • CTE (25 – 500 °C) = 13.8 μm/m*K
  • Laserable and solderable
