During the operation of food and medical machinery, they constantly face various complex challenges such as acid alkali corrosion, electrochemical corrosion, high temperature, and wear. The safety of materials has always been a focus of attention in the industry. The cobalt based alloys produced by Bzzalloy have FDA certification and ISO13485 medical device management system certification, which can be safely applied in these fields. Due to the presence of cobalt, chromium, molybdenum, tungsten and other components in Stellite alloy, it has higher wear and corrosion resistance, and is widely used in industries such as homogenizers, sealing tools, cutting tools, and artificial joints.
