摘要： An improved wire used as an electrode in electrical discharge machining is proposed which has higher tensile strength at high temperatures. It is a composite wire comprising a core of stainless steel and a covering layer of copper or copper alloy provided around the core. The diameter and the tensile strength of the wire and the percentage of the sectional area of the core to that of the entire wire are specified.

摘要： The ferrite/stainless steel weld material of the invention contains the following constituents: 0.03% by weight or less of carbon, 1.00% by weight or less of silicon, 1.00% by weight or less of manganese, 16.0 to 21.0% by weight of chromium, 0.30 to 0.80% by weight of niobium, 0.30 to 0.80% by weight of copper and 0.025% by weight or less of nitrogen, the remainder being iron. The ferrite/stainless steel weld material of the invention gives good weldability not only in the welding of stainless steels of the same type, but also in the welding of stainless steels of different types. In addition, the welding steel of the invention has good oxidation resistance, good workability and good mechanical properties.

摘要： PURPOSE:To enhance the tensile strength and heat resistance of a cut wire under normal and high temperature conditions by forming the cut wire in a three layer cross-sectional structure having an outermost brass layer, a second copper layer and an austenite group stainless steel core. CONSTITUTION:A cut wire has a three layer cross-sectional structure having an outermost brass layer 3, a second copper layer 2 and an austenite group stainless steel core 1. With this arrangement, due to the contribution of the austenite group stainless steel core 1, the entire tensile strength and high temperature resistance strength of the cut wire are increased so that the wire is hard to break, and therefore, working is not interrupted while a manless process using an automatic processing machine is made to be possible. Further, the provision of the second copper layer 2 ensures a sufficient electric conductivity so that a higher capacity current may be fed. Since the wire cut has a high strength and is therefore never softened even though a high capacity current is fed, it is possible to enhance the tensile strength of the out wire, resulting in an increase in processing speed. Further, the brass layer 3 is more evaporative than the steel so that adhesive to a workpiece is decreased due to the evaporation of the brass layer, and therefore, a cut surface having a satisfactory surface roughness may be obtained.

摘要： PURPOSE:To produce a plated wire having superior workability and corrosion resistance with no damage to the plating when an Au or Ag plated wire is produced, by successively subjecting a wire rod to predrawing, soln. heat treatment, plating and finish drawing to specified tensile strength. CONSTITUTION:When an Au, Ag or Au-Ag alloy plated wire is produced as a high strength spring material or a contact material having superior solderability, corrosion resistance and contact resistance, a wire rod of steel, stainless steel, Ni, an Ni alloy, Ti a Ti alloy or a Cu alloy is predrawn into a wire. This wire is heated, subjected to soln. heat treatment, plated with Au, Ag or an Au-Ag alloy and finish-drawn to tensile strength satisfying inequality I [where Ts is the tensile strength (kg/mm ) of the wire and d is the diameter (mmphi) of the wire]. A smooth plated wire having satisfactory adhesion between the plating and base wire, superior corrosion resistance and workability is obtd.

摘要： PURPOSE:To improve the accuracy of electric discharge machining and the working speed by using a composite wire for a cut wire having a core of steel or stainless steel of 0.05-0.4mm diameter covered with copper or copper alloy layer, occupying 30-90% of the whole sectional area of core and having 40-200kg/cm of tensile strength. CONSTITUTION:A core 2 made of steel, stainless steel or the like is plated or cladded with copper or copper alloy layer 3. And assuming that the wire diameter is 0.05-0.4mmphi, the sectional area of core 2 is SI and the sectional area of plating layer 3 is SII, SI/(SI+SII) is set to 0.3-0.9 and the tensile strength is set to 40-200kg/cm . When this is used for a cut wire, high tensile strength is ensured under room and high temperatures, necessary and sufficient conductivity for electric discharge machining is ensured by the plating layer 3, and working accuracy and speed are improved. Also the values within these range are the most suitable so that sufficient properties are not obtained in values more than or less than said ones.
