Keralloy KB

Non precious casting alloy based on cobalt for metal-ceramic accord. DIN EN ISO 22674, type 5.

Because of the low vickers hardness Keralloy® KB allows an optimal preparation and polishing. The alloy is very flexible during handling, ideal for crowns and bridges and milling work. It can be bonded with all standard high sintering porcelains.
Keralloy® KB is high corrosion-resistant and free of beryllium, indium and gallium.
