Abstract:
An aluminum or aluminum alloy-coated steel material includes base steel; and a coating layer formed on a surface of the base steel and containing by mass % Mg: 6% to 10%, Si: 3% to 7%, Fe: 0.2% to 2%, Mn: 0.02% to 2%, and the balance as Al and incidental impurities, where-in the coating layer has pseudoternary eutectic microstructures of αAl—Mg2Si—(Al—Fe—Si—Mn) and an area ratio of the pseudoternary eutectic microstructures in the coating layer is at least 30%.
