Abstract

PURPOSE:To make a printing wire for a dot printer endurable for use at high speeds and for a long time and able to keep its printing quality steadily by making the wire of a WC-base cemented carbide which includes Co as a bonding material within a restricted range and has a hardness value and a Young's modulus within restricted ranges. CONSTITUTION:A printing wire 1 for a dot printer has a terminal 2 operted by an armature 3 on one end, the other end of the wire is arranged to perform printing action on a recording paper 5 guided by a bearing 8, and the wire is required to be endurable for use at high speeds and for a long time. To satisfy the requirement, a WC-base cemented carbide is selected for the material of the printing wire 1 restricting the range of Co as a bonding material within 10-20 weight %, restricting its hardness value within 38-92 in Rockwell A scale and its Young's modulus within 50000-58000 kg/mm<2>, and the wire is annealed being heated to about 1000 deg.C in hydrogen or vacuum after formed by grinding.
