  • Aluminum-base alloy used as material for galvanic protector
    Patent number: 4240829
    Abstract: An aluminum-base alloy used as the material for galvanic protector and consisting essentially of about 0.005 to about 3.5 weight percent gallium, about 0.1 to about 1.0 weight percent magnesium and the balance being essentially aluminum.The alloy is made up of readily available components, affords effective corrosion protection to iron and steel when in contact with aqueous salt solutions of various concentration (from 10 mg/l to a saturated aluminum solution). The alloy exhibits high electrochemical properties, namely: a current density in natural water with a total concentration of salts ranging from 100 to 200 mg/l is 2 ma/dm.sup.2, and in a saturated calcium sulfate is 10 ma/dm.sup.2. The electrochemical activity of the alloy is smoothly regulated by the quantitative composition thereof.
