A BEGO solder for cobalt-chrome framework alloys
Kobalt-Chrom-Lot is a filler material intended for laboratories performing soldering work on cobalt-chrome structures, particularly in removable partial denture prosthetics.
Its purpose is to provide a joint that is consistent with the Co-Cr alloys used for frameworks, clasps, metal saddles and assembly areas in removable partial dentures.
Thanks to its rod format, the laboratory can dose the solder filler precisely according to the size of the joint and the area to be brazed.
For Co-Cr metal frameworks
This solder is indicated for cobalt-chrome alloys used in removable partial denture framework work.
- Soldering of cobalt-chrome metal frameworks.
- Assembly or repair of cast partial framework structures.
- Work on compatible Co-Cr alloys.
- Laboratory procedures on removable partial denture metal frameworks.
For non-precious alloy work
Kobalt-Chrom-Lot is a solder for non-precious alloys, suitable for cobalt-chrome dental components requiring technical brazing.
- Solder filler application on non-precious Co-Cr metals.
- Repair of metal elements according to compatibility.
- Work requiring good flow properties.
- Use with a suitable flux, particularly Minoxyd.
Cobalt-chrome composition suited to metal frameworks
BEGO Kobalt-Chrom-Lot solder is based on a cobalt and chromium composition, with silicon, molybdenum, boron, iron and carbon.
This formulation is suited to work on cobalt-chrome alloys used for removable partial denture frameworks, with a high melting range allowing work on compatible non-precious structures.
Surface preparation, flux selection, component stability and heat control remain essential to obtain a clean and resistant solder joint.
Solidus / liquidus range 1125–1195 °C
BEGO data indicate a solidus temperature of 1125 °C and a liquidus temperature of 1195 °C.
- High-fusing solder for Co-Cr alloys.
- Progressive heating recommended.
- Thermal control is essential.
- Adjustment according to the mass of the part to be brazed.
Working around the fusion zone
The commercial product sheet mentions a working range around 1100 to 1150 °C. BEGO catalogue data should remain the technical reference for solidus and liquidus values.
- Increase temperature evenly.
- Avoid localised overheating.
- Control the flow of the solder.
- Follow the laboratory protocol.
Use with Minoxyd flux REF 52530
The BEGO catalogue associates Kobalt-Chrom-Lot with Minoxyd flux, reference 52530.
The flux helps prepare the brazing area, limit oxidation during heating and promote wetting of the solder on properly prepared cobalt-chrome surfaces.
Flux selection is important: an unsuitable flux or poorly prepared surface can compromise flow behaviour and the final quality of the joint.
Benefits for the laboratory
- BEGO solder dedicated to cobalt-chrome alloys.
- Suitable for metal frameworks and cast partial denture structures.
- Co-Cr composition consistent with non-precious alloy work.
- Practical rod format for localised filler application.
- Minoxyd flux identified as the associated reference.
Kobalt-Chrom-Lot allows the laboratory to keep a specific solder for repairs, additions or assemblies on cobalt-chrome frameworks.
Benefits for soldering
- Good flow properties when the protocol is followed.
- Joint suited to compatible Co-Cr alloys.
- Controlled filler application thanks to the rod format.
- Strength suited to dental metal assemblies.
- Finishing can be controlled after cooling and cleaning.
The final quality depends on joint fit, surface cleanliness, flux, temperature and post-brazing treatment.

Preparation of components before brazing
Cobalt-chrome alloys require rigorous preparation before soldering. A contaminated, oxidised or poorly fitted surface can affect solder flow and the quality of the joint.
Before heating
- Clean the metal surfaces to be joined.
- Remove visible oxides and contamination.
- Check the fit and stability of the components.
- Apply Minoxyd flux or a compatible flux according to protocol.
During brazing
- Heat the area progressively and evenly.
- Control the application of the solder rod.
- Avoid localised overheating of the framework.
- Observe the wetting of the solder on the prepared surfaces.
Instructions for laboratory use
Kobalt-Chrom-Lot solder must be used by a professional trained in high-fusing dental brazing. The protocol must be adapted to the alloy, the framework thickness and the type of repair or assembly.
- Check compatibility with the cobalt-chrome alloy used.
- Prepare a clean, stable and properly accessible joint.
- Use a flux suitable for Co-Cr alloys.
- Heat progressively to avoid thermal stresses.
- Clean and inspect the solder joint after cooling.
Good visibility of the brazing area and stable positioning of the components help improve the precision of the procedure and the consistency of filler application.
Inspection and finishing after brazing
After soldering, the assembled area should be inspected before the framework finishing stages.
- Allow cooling according to the laboratory protocol.
- Remove flux residues.
- Inspect the continuity of the soldered joint.
- Sandblast or grind according to the alloy recommendations.
- Check the integration of the repair before final polishing.
Final cleaning provides a readable surface and makes it possible to verify that the solder is correctly localised and homogeneous.
