Solder alloy based on nickel is composed of a mixture with a first soldering material, a second soldering material, and a base material, wherein the base material is a nickel-based material which corresponds to the material to be soldered and is present in a proportion of 45-70% by weight in the mixture, the first soldering material is a nickel-based material including chromium, cobalt, tantalum, aluminum and boron, and is present in a proportion of 15-30% by weight in the mixture, and the second soldering material is a nickel-based material including chromium, cobalt, molybdenum, tungsten, boron and hafnium, and is present in a proportion of 15-25% by weight in the mixture.

Nickel-based solder alloy

The invention relates to a generative production method for producing a component by selectively melting and/or sintering a powder several times consecutively by introducing an amount of heat by means of beam energy, such that the powder particles melt and/or sinter in layers, wherein the powder particles () are made of a first material () and the powder particles are surrounded by a second material () partially or over the entire surface thereof, wherein the second material has a lower melting point than the first material and/or lowers the melting point of the first material when mixed with the first material. The invention further relates to a corresponding powder and to a prototype produced from said powder.
