Abstract: An aluminizing alloy consisting essentially of about 0.75 to 4.0 percent manganese and the balance aluminum and impurities. The alloy when applied to a ferrous article by immersion of the ferrous article in a molten bath of the alloy providing a surface coating of higher brightness and uniform smoothness. The impurities may include up to 0.20 percent silicon, up to 0.35 percent iron and up to 0.02 percent copper. A composite article having a ferrous core and a coating of the aluminum base manganese alloy. A method of producing a hot dip aluminized ferrous article having a bright finish comprising providing a molten bath of an aluminum base alloy at about 1,250* to 1,400* F. and immersing a ferrous article in the bath for about 1 to 6 minutes. The aluminum base alloy consisting essentially of 0.75 to 4.0 percent manganese and the balance aluminum and impurities.
