Heraenium® P - for C& B
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.

HeraCeram: Rapid cooling At the end of the program the firing platform is completely and firing tray with objects is removed immediately. The firing tray can cool next to the furnace on a fire-resistant tray. Others: Normal cooling (Stress relief cooling) The firing platform is driven down at the end of the program and the firing tray is left in the radiated heat for 2 – 3 minutes before it is removed. |

Explanation of abbreviations and numbering:
x = content < 0.1 mass%
Indications:
1 Inlays, cervical filling
2 MOD Inlays
3 Crowns
4 Bridges
5 Milling technique
6 Partial dentures
10 Cast posts
14 Can be veneered with high expansion, low-fusing ceramics
15 Implant restorations
16 Electroformed double crown technique (primary crowns)
Abbreviations:
w = after soft annealing and quenching
k = ceramic bonding alloy: condition after ceramic firing
v = after hardening
s = self-hardening after slow cooling in the mould
A = A stable framework design with reinforced connections with a cross section of 8 - 10 mm² is required for long span bridges and superstructures. Additionally, the frameworks need to be hardened.
B = Depending on the copper content, in some cases discolouration ofdouble crowns may result after short period of wearing. Discolouration, however, is technically and physiologically harmless.
C = In exceptional cases these alloys can also be used for traditional telescopic crowns with parallel walls and for the bar casting technique provided that cross-sections for crown walls, approximal areas, bars and laser welded joints are particularly thick and the alloy is hardened subsequently. No indication for conical crowns and sheardistributors.
Please observe instructions for use included during delivery when processing of the alloy!
