Stellite Alloy of Shenyang Top New Material Co., Ltd. - Cobalt Chrome Alloy
Generally, cobalt-based superalloys lack a coherent strengthening phase. Although the medium temperature strength is low (only 50-75% of nickel-based alloys), it has higher strength, good thermal fatigue resistance and hot corrosion resistance above 980 °C. And abrasion resistance, and has good weldability.

16: Dental Casting Alloys and Metal Joining | Pocket Dentistry
Alloy Classification by Noble Metal Content. In 1984, the American Dental Association (ADA) proposed a simple classification for dental casting alloys based on the content of noble metals. Three categories were described: high noble (HN), noble (N), and predominantly base metal (PB). This classification is presented in Table 16-1.
