Abstract
The paper presents the characteristics and systematics of commercial cobaltbased
alloys. The focus is mainly on the alloy, which are widely used in prosthetic dentistry
in many dental laboratories. Cobalt alloys, various manufacturers were ranked based
on the content of the main component (Co), mechanical properties, applications. The aim
of this work was to facilitate the selection of the cobalt-based alloys in the course of
construction and prosthetic work.
