PRINTING WIRE FOR PRINTER

PURPOSE:To provide wt. reduction and high speed printing operation and to obtain excellent durability by enhancing hardness and reducing abrasion, by forming a printing wire by processing a sintered body of doped molybdenum containing one or more kind of aluminum, silicon and potassium. CONSTITUTION:A printing wire is formed by processing a sintered body of doped molybdenum containing one or more kind of aluminum (Al), silicon (Si) and potassium (K) and, if surface reducing processing is applied to the sintered body comprising the doped molybdenum, a high hardness product can be obtained by the actions of Al, Si and K. The compositional range of Al. Si and K is set to 0.005-0.75% on a wt. basis and, if the contents thereof are too little, effect is reduced and, if too much, the surface reducing processing is difficult. The doped molybdenum powder having one kind or plural kinds of Al, Si and K added thereto in a predetermined ratio is pressed to mold a compacted powder which is, in turn, sintered to obtain the rod-shaped sintered body. Next, rolling processing and wire drawing processing are applied to the sintered body to form a wire material which is, in turn, cut into a predetermined length to form the printing wire.
