AZ31B is a wrought magnesium alloy containing aluminum and zinc, commonly used in aerospace structural components, automotive parts, and portable equipment where light weight is critical. The O (annealed) temper provides optimal ductility and formability with reduced strength compared to work-hardened conditions, making it suitable for applications requiring complex forming operations and moderate loads at temperatures up to approximately 150°C.
