Magnesium Elektron Elektron® ZK60A Magnesium Alloy, UNS M16600
Categories:	Metal; Nonferrous Metal; Magnesium Alloy
Material Notes:	ZK60A is a wrought magnesium base alloy containing zinc and zirconium. Increased strength is obtained by artificial aging from the as-fabricated form. ZK60A-T5 has the best combination of strength and ductility at room-temperature of the wrought magnesium alloys. Applications: Forgings in ZK60A find application in high strength parts for use primarily where the service temperature is below 150°C. ZK60A forgings can be used where pressure tightness or machinability are required. That parts are dimensionally stable during and after machining is also an important design consideration. Forgings in ZK60A find application in high strength parts for satellites, helicopter gearboxes and rotor hubs, bicycle frames, road wheels, missile frames and interstage fairings, brake housings and landing gear struts.
