Material Overview
Co12 is a high-carbon, high-tungsten cobalt-based superalloy designed for extreme temperature, high pressure, and severe wear environments. Based on cobalt (Co), it incorporates chromium (Cr), carbon (C), tungsten (W), and other elements (Fe, Ni, Si) to achieve enhanced strength, thermal stability, corrosion resistance, and superior (wear resistance). Compared to Co6, Co12 features significantly higher carbon (1.5%) and tungsten (8.0%) content, prioritizing hardness and high-temperature performance at the expense of toughness, making it suitable for more demanding applications.
