Cast partial denture
Alloys
remanium® GM 280
Spring hard alloy with reduced hardness for the
cast partial denture technique.
Product advantages:
• 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 properties
Indication: cast partial dentures
Norm: DIN EN ISO 22674 (type 5)
