ZIRCADYNE 702 is described as unalloyed zirconium despite the fact that it contains hafnium (4.5% max.) from its ore. Hafnium is very similar to zirconium metallurgically and chemically and is not detrimental to corrosion resistance and other characteristics of zirconium in most applications (except nuclear). Because of its excellent resistance to many corrosive media and its good mechanical and heat-transfer properties, Zircadyne 702 has found widespread use in many chemical process applications. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as fatigue. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Zr-7. Producer or source: Teledyne Wah Chang Albany.
