  • Method of improving the ductility of the coating of an aluminum-zinc alloy coated ferrous product
    Patent number: 4350539
    Abstract: This invention relates to an aluminum-zinc alloy coated ferrous product whose coating is highly ductile, and to the method whereby such improved coating ductility may be realized. The process is characterized by the steps of thermally treating the aluminum-zinc alloy coated product by heating to a temperature between about 200.degree. F. (93.degree. C.) and 800.degree. F. (427.degree. C.) and holding for a period of time to effect metallurgical structure changes, among them being the precipitation of a second phase incoherent with the matrix, followed by slow cooling to at least 400.degree. F. (205.degree. C.). The resulting product is characterized by an aluminum-zinc alloy coating with a hardness no greater than about 115 VHN, and preferably no greater than about 110 VHN.
    Type: Grant
