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!
