Cobalt #1 is designed for applications that require extreme abrasion resistance at elevated temperatures, but where impact resistance is not a consideration. Cobalt #1 has a higher carbon and tungsten content than other cobalt alloys causing the weld deposit to have a higher volume of carbides within its microstructure. Although the weld deposits of Cobalt #1 are not as “tough” as those of Cobalt #6, they are much harder and have excellent resistance to solid particle erosion.
