Valve metal articles such as wire, sheet or powder having a second metal, preferably in a peripheral margin, prepared by coating the valve metal with a salt solution of the metal additive and heat treating in the presence of an oxygen getter to remove the oxygen from the valve metal and the anion of the metal salt to form the metal additive. For tantalum wire a preferred second metal is nickel. A preferred oxygen getter is magnesium. Nickel-containing tantalum wire is useful for enhance bonding to sintered pressed tantalum powder pellets in the production of electrolytic capacitors.
