Claim 12:
13. A method for brazing a plate heat exchanger comprising a number of heat exchanger plates being provided with a pressed pattern of ridges and grooves adapted to provide contact points between neighboring heat exchanger plates, such that the heat exchanger plates are kept on a distance from one another and such that interplate flow channels for media to exchange heat are formed between the heat exchanger plates, the method including the steps of
applying the brazing material of claim 1 to selected areas of the heat exchanger plates,
bringing the number of heat exchanger plates together,
heating the brazing material to a maximum temperature above the liquidus temperature of the first grains but below the solidus temperature of the second grains.
