Alloy 1 (UNS R30001) is a cobalt-chromium-tungsten alloy engineered for extreme wear resistance, high hardness (50-58 HRC), and excellent corrosion and oxidation resistance at elevated temperatures. With high carbon (2-3%) and tungsten (11-13%) content, it provides superior resistance to metal-to-metal wear, galling, erosion, and thermal fatigue. This alloy is primarily used for hard-facing and CNC-machined components in valve seats, pump plungers, and cutting tools .
