The present invention provides an orthodontic metal arch wire having a wire comprising a metal alloy, e.g., "shape memory" alloys, formed into an arch shape, and a metal layer provided on at least a portion of the wire such that an auxiliary part either is to or can be soldered to the metal layer. The metal layer provided on the arch wire can be a noble metal layer, e.g., gold, platinum, rhodium and palladium, or a layer of tin-nickel or palladium-nickel. An auxiliary part, such as a post, hook or loop, can then be soldered or brazed to the metal layer.
