Cobalt 6B is tough and wear resistant. It balances the properties of alloys with higher and lower carbon content, and is known for its all-around performance. With a wrought material structure, it withstands rapid changes in temperature, resists abrasion, and is four times as impact resistant as other cast materials made from the same chemicals. It won’t corrode or oxidize in extreme environments, so it’s commonly used in food-handling machinery and chemical equipment. Cobalt 6B slides against other materials without degrading, seizing, or galling, making it a good choice in areas that can’t be lubricated or for sliding parts such as sleeves. It also retains its properties at high temperatures. Unlike pure cobalt, it’s nonmagnetic, so it won’t cause damage when used in electrical systems. It’s also known as Haynes 6B and Stellite® 6B.
