Also known as Haynes 6B, alloy 6B, and Stellite® 6B, Cobalt 6B is a tough and wear-resistant cobalt alloy. 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, making it good for use in food-handling machinery and chemical equipment.

Cobalt 6B balances the properties of alloys with higher and lower carbon content, and is known for its all-around performance. It slides against other materials without degrading, seizing, or galling, so it’s often used in areas that can’t be lubricated or for sliding parts such as sleeves. Cobalt 6B maintains its properties at high temperatures. Unlike pure cobalt, it’s nonmagnetic, so it can be used for parts in electrical systems.
