PRODUCT INTRODUCTION

            

WISDOM Stellite's cobalt base alloys are available as cobalt rods, cobalt electrodes, cobalt wire and cobalt powder.  Cobalt alloys are used primarily for wear applications, our cobalt alloys can be applied by any known fusion welding process or HVOF spraying proess and are particularly well-suited for hardfacing applications.  Cobalt alloys are the most widely used wear resistant hardfacing materials available.  Their unique combination of wear resistance, strength and corrosion resistance make them adaptable to many harsh environments.  Cobalt alloys are selected for their excellent resistance to the widest combination of wear types including adhesive wear, abrasion, erosion, contact fatigue, thermal shock, cavitation wear, corrosion and oxidation.  The degree to which the cobalt alloys retain these properties assures their unique position in the wear technology field.
