Abstract

Zn-RE alloy coating material and its production are both disclosed herewith. The alloy also comprises added elements 0.5% in total, selected from Fe, B, Pr, Nb, Pb, Cu, Sn, Bi, Ni, and Sb, one or some of them at least. It is produced by: proportioning, smelting at 700-850 deg.C, stirring, refining, and casting into ingots. The coating material has good corrosion-proof and anti-fatigue performances, and good binding ability so as to be used in domestic electric appliance, construction materials or automotive industries.

Description

technical field [0001] The invention relates to a binary alloy coating material and a manufacturing method thereof, in particular to a binary alloy coating material of high corrosion resistance coated steel and a manufacturing method thereof. Background technique [0002] In the current domestic and foreign markets, due to the increasing demand for hot-dip galvanized or hot-dip galvanized alloy steel sheets in the fields of household appliances, building materials, and automobiles, most manufacturers are still producing and using traditional hot-dip galvanized steel sheets (with ) or hot-dip galvanized steel sheet (strip) containing only 0.1 to 0.2% Al, the so-called binary alloy hot-dip galvanized steel sheet (strip). There are many defects in this product, the service life is short, and the defect of rust occurs in only about 10 years, and the mechanical processing performance is poor, and the coating is easily damaged due to stretching, especially under the condition of h...
