Phantom metal

Phantom metal is used in dentistry (sub-area: dentures ) for cost reasons for training purposes instead of gold alloys for the production of dental crowns and bridges . The alloy consists of:

• Copper 87.5 mass%
• Zinc 1 mass%
• Tin 9 mass%
• Cobalt 2.5 mass%

Various plumb bobs are also available.

The melting range is 770 to 880 ° C. The use of plaster-bonded investments is therefore possible. Phantom metal is not biocompatible , so it is not used in patients. The initially gold-like color soon oxidizes bluish-purple. The vapors released during processing should, if possible, not be inhaled.
