Nickel Filler Metal 61 is a nickel-base alloy that is used for welding Nickel 200 and Nickel 201 to themselves and to other alloys such as stainless steel, carbon steels, copper-nickel alloys, INCONEL alloys, INCOLOY alloys and MONEL alloys. The weld metal has moderate strength and ductility and good resistance to corrosion, particularly in alkalies. This datasheet provides information on composition and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Ni-308. Producer or source: Huntington Alloys.
