                Chiamger, as a new brand, is initiated specially for hardfacing materials by WISDOM on Jan 1st, 2016. They are used primarily for wear application, our cobalt alloys can be applied by various fusion welding process or thermal spraying process and are particularly suitable for hardfacing applications.  Our cobalt alloys are adaptable and can be refined for a range of special applications. Their unique combination of wear resistance, strength and corrosion resistance make them applicable to many harsh environments.

                Our Cobalt hardfacing alloys are selected for their excellent resistance to the widest combination of wear-resistant applications. The degree to which the cobalt alloys retain these properties insures their particular position in wear technology area.

                The Wisdom's cobalt base welding materials are available in forms of rod, electrodes and powder. Regarding rod and electrode, they are equivalent to Stellite, Tribaloy, Bishilite, Stoodite and Tribaloy welding rod and electrode. Strictly in accordance with AWS, ASME and UNS standard, Wisdom's cobalt metals can be classified in following specifications.
