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.
