PROBLEM TO BE SOLVED: To provide a material for a welding structure which is light in weight, and moreover, excellent in weldability, and also, to provide a welding structure member formed of the material. SOLUTION: A clad material is provided. The clad material is provided with a base material layer 2 formed of pure Al or an Al alloy and a welding layer 3 diffusion-joined to the base material layer. The welding layer 3 is formed of an Ni-Cu alloy containing Ni of 20-70 mass %. The welding layer 3 may be formed at a part on the surface of the base material layer 2. Also, it is preferable that both surfaces of the base material layer 2 are coated with the welding layer 3. COPYRIGHT: (C)2004,JPO&NCIPI |
