remanium® CoCr alloys at a glance.
remanium® star remanium® secura Characteristics Modern bonding alloy type 5 with excellent processing
characteristics and low hardness. Suitable for all processing
technologies.
CoCr bonding alloy type 5 with maximum reliability
potential during processing. Excellent casting behavior,
also for vacuum / pressure casting.
Product advantages extremely easy to work with, especially when milling
or polishing due to the reduced hardness
suitable for processing technologies such as casting,
milling and laser melting
excellent veneerability because of the
low thermal expansion coefficient
oxide firing is not necessary
long-term cooling is only recommended
with long-span bridges
particularly recommended for telescopic work
suitable for laser welding since carbon-free
reliable melting and casting characteristics, especially
with vacuum/pressure casting, resulting from the
narrow melting range
small ingots (4 g) allow exact portioning of the alloy:
ideal and economical filling of the crucible
no danger of spattering or increased slagging
high mechanical strength thanks to tantalum
mixed-crystal reinforcement
optimized bake behavior of the veneering ceramic
through low oxidation

Safety through certified quality Best biocompatibility: Laboratory tests confirm the outstanding corrosion resistance, and tests conducted by independent institutes acknowledge the
biological compatibility on the basis of cytotoxicity tests. Please inquire for our certifications. All CoCr crown and bridge alloys are free of beryllium, iron
(except remanium® LFC), nickel, gallium, indium and copper.
