Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a material exhibiting excellent weldability as well as good thermomechanical properties and used as a crucible for a melting device and a remelting device. SOLUTION: A copper alloy having a composition containing 0.2 to 1.5% Ni, at least one kind of element selected from the groups consisting of phosphorous, aluminum, manganese, lithium, calcium, manganese, silicon and boron of 0.002 to 0.12%, and the balance copper with impurities caused by the production is used as the material in an unhardened state, e.g. for the production of a crucible for a melting device and a remelting device. For intentionally improving its strength, the copper alloy may contain zirconium of
