Abstract

PURPOSE:To obtain a hammer of excellent wear resistance and corrosion resistance and a long service life by forming a contactor with a special wear-resistant alloy. CONSTITUTION:Dot printing is conducted by hitting an ink ribbon 4 and a recording paper at a high speed with a projection 1 of a spring plate 3 by action of an electromagnet. At this time, a contactor 14, which is formed with a wear-resistant alloy consisting of a platinum group metal and a transition metal or an alloy consisting of a platinum group metal, a transition metal and boron, is attached into the tip of a member 12 for the projection, and further, these are tapered off toward the top end to provide a print hammer. As to the alloy in question, it is preferably to use an alloy consisting of 50 wt% of Os and 50wt% of Ir.
