This new ceramic alloy is for special

low-fusing and high-expanding ceramics for bake-on technique.


It is free from nickel and biocompatible on a cobalt-chrome-molybdenum basis with outstanding corrosion resistance and good strengths properties.


This alloy features good milling, polishing and very good laser welding.

ADORBOND CLF is made in compliance with the DIN EN ISO 9693 standard.


Waxing up:

Wall thickness (in wax) should not be less than 0.35 mm diameter. Apply indirect spruing. Guide round wax profiles with a diameter of 3.5 to 4mm in flow direction of the melt avoiding sharp angles. For large structures with 4 pontics and more use a feed channel of 0.4 mm.

Investing and Casting

Phosphate-bonded crown and bridge investment materials can be used. The preheating temperatures range between 850 and 950 °C according to the type of investment material and the casting machine. The holding time after the final temperature has reached is between 45 and 60 minutes according to the cast ring (muffle) size and filling degree of the furnace. It is imperative to follow the relevant casting machine manufacturer's instructions for use. Use always a new ceramic crucible for ADORBOND CLF to avoid contaminations which may occur by residuals from previously used alloys. Casting should be started after all cylinders are completely melted and the melt shows a uniformly light appearance. When melting with the torch, take care that the correct flame is adjusted according to the manufacturer's instructions. With a loose circular motion of the flame in the reducing zone, continue the melting process until the metal is seen to move under the pressure of the flame. Do not overheat. Allow casting ring (muffle) to cool down and deflask it. Sandblast the casting carefully at a pressure of 4 bar using corundum.

Ceramic build-up

Commercially-available low-fusing and high-expanding standard dental ceramics can be used. Observe the relevant instructions for use. After separation of the sprues and finishing:

  1.   Sandblast the framework surface in a pencil blaster using aluminium oxide 100 or 250 μm.
  2.  Clean the framework with distilled water in an ultrasonic bath, or degrease in ethyl acetate.
  3. Carry out oxide firing for 5 minutes at approx. 800 °C.
    Always sandblast the oxide layer again after the oxide firing!
  4. Apply a thin layer of opaque. Apply uniform cover only at the second opaque firing.
    Always allow past opaque to cure before heating.

  5. Ceramic build-up according to the porcelain manufacturer's instructions.
  6. Cool down after firing observing the porcelain manufacturer's instructions.

Final work

After completion smoothen the framework with rubber polishers and polish to high lustre using a polishing paste for cobalt-based alloys.

Soldering and Welding

Use a cobalt-based solder and high-temperature flux for soldering. For laser welding use a standard Co-Cr laser wire as filling material.

Safety hints

Metal dust is harmful to your health. When finishing and blasting us a suction/extraction system.
