remanium® cast partial denture alloys at a glance.
remanium® GM 800 + remanium® GM 380 + remanium® GM 900 remanium® GM 280
Characteristics Extra spring-hard universal alloy
with a high yield strength for all
types of cast partial denture
work, type 5.
Time-tested, spring-hard alloy for
all types of cast partial denture
work, type 5.
Extra spring-hard, modern alloy
for all types of cast partial
denture work. Excellent laser
welding properties as it is
carbon-free, type 5.
Spring hard alloy with reduced
hardness for the cast partial
denture technique.
Product advantages high modulus of elasticity for
delicate, yet stable frameworks
high fracture resistance due to
excellent mechanical properties
mirror effect on melt surface
high-luster surfaces after
electrolytic polishing
mirror effect on melt surface
easy preparation and polishing
easily activated, high yield
strength
harmoniously coordinated,
high mechanical parameters
easy preparation and polishing
due to reduced surface
hardness
mirror effect indicates the
appropriate moment for
casting. Prevents overheating
of the molten alloy, ensuring
smooth clean castings.
excellent laser welding
properties as it is carbon-free
the low hardness enables easy
finishing and polishing
high elongation at rupture
prevents clasp fractures
mirror effect indicates the
appropriate moment for
casting. Prevents overheating
of melt
very good laser welding
