摘要： A method of manufacturing a welding electrode or filler rod by cleaning the surface of an aluminum wire rod and applying to the cleaned surface an aqueous solution of an alkali metal silicate having a concentration of greater than 0.5 percent for a period of greater than 5 seconds at a temperature in excess of 140*F in order to establish a thin, oxidation resistant reacted silicate coating on the aluminum surface. Subsequently rinsing and drying the coated aluminum wire or rod. The reacted silicate coating is provided in such a fashion that it has a thickness such that the outermost 1,000 angstroms of the aluminum surface has about 0.10 to 1.25 percent silicon. An aluminum welding rod or electrode having a thin reacted oxidation barrier coating on the exterior surface thereof. The oxidation barrier coating is such that the outermost 1,000 angstroms of the wire surface contains about 0.10 to 1.25 percent silicon and preferably about 0.50 to 0.80 percent silicon. The oxidation resistant coated surface is characterized by resistance to appreciable crazing and flaking responsive to deformation of the aluminum wire.

摘要： A composite clad sheet product made up of an aluminum base alloy containing about 2.5 to 6% zinc, about 0.4 to 3% magnesium, about 0.2 to 1% manganese, and balance essentially aluminum, clad with a magnesium-free aluminum base alloy containing about 0.5 to 1.8% manganese. The product may have an outside porcelain enamel finish and an inside cured organic resin finish and be in the form of a cooking utensil.
