ELEKTRON ZW1 is similar to ELECTRON ZW3 but with reduced zinc content to confer complete freedom from junction cracking in manual argonarc or heriarc welding, with but small sacrifice in strength properties. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, machining, joining, and surface treatment. Filing Code: Mg-16. Producer or source: Magnesium Elektron Inc..
