PURPOSE:To provide a welding wire having excellent welding performance and high electrical conductivity, by incorporating a specific amt. of Mn, further contg. at least 1 kind among P, Li, B and consisting of the balance Cu. CONSTITUTION:A welding wire consists of 0.1-0.4% Mn, contains further at least 1 kind among respectively 0.005-0.3 P, Li, B and consists of the balance C. Said wire has high electrical conductivity and excellent welding workability. Such wire is ideally suited for welding the cooling plates and tuyeres for blast furnaces and electrical parts of others where the high heat conductivity is expected. The workability, strength, bending, etc. in welding are practically the same as those of commrcially available welding wires, and there is no decrease in the welding performance that occurs in the increased conductivity. |
