PURPOSE:To improve the high temp. strength of a product by heating in an inert gas atmosphere after overlapping a sheet after forming one layer at least of the layer composed of a W wire and the brazing filler metal layer containing the element having lower melting point further on the surface of a iron base alloy sheet. CONSTITUTION:A sheet and brazing filler metal are integrated by coating the sheet like brazing filler metal consisting of the melting point reducing element of B, Si, Al, etc., for instance, by low temp. plasma spraying, etc. on the surface of the sheet of the iron base alloy containing at least one layer of the layer which is composed of W wire, further by laminating a sheet and in succession by holding with heating at the temp. more than the melting point of the brazing filler metal and less than the melting point of the iron base alloy. In this way, the product having excellent high temp. strength can be obtd.
