Patent ID: 8704136

Claim:
Filler material for thermal production of a joint or of a metal layer metallically connected to base material of or on an object of at least one of light metal, light metal alloy and zinc alloy wherein each of the light metal, light metal alloy and zinc alloy has a thermal conductivity of more than 110 W/mK, the filler wire comprising: a filler wire including a sheath with a conductivity of 0.027 to 0.2 μΩxm comprising at least one metal of aluminum, magnesium, and zinc, or a deformable alloy of one or more of these metals wherein the alloy has a thermal conductivity of more than 110 W/mK; a core of compacted powder including core material comprising at least one of a metal powder, a powder of at least one metal compound, a non-metallic compound, an agent giving off gas at increased temperature, and at least one component forming slag; and an outer surface of the filler wire including a layer formed of at least one organic polymer and graphite, and volume fraction of the graphite in the layer is 15% to 45%.
