This invention relates to methods for soldering metals to superhard man-made materials such as diamond, boron nitride and hexanite and to soldering agents therefore. A method is proposed which comprises applying a metallizing coating to the soldering surface of the materials based on diamond and/or boron nitride, the materials to be joined by soldering being exposed to a temperature sufficient to bring about adequate adhesion of the metallizing coating to the materials to be soldered, and subsequently soldering the metal with the material bearing the metallized coating by use of soldering agents featuring ductile properties and melting points in the range up to 1,000.degree. C, whereby, in accordance with the invention, the metallizing coating is constituted by metals showing high adhesive activity toward materials based on diamond and boron nitride and accounting for from 3.0 to 65 percent by weight of the coating and by metals showing poor oxidizability which account for the balance. The soldering procedure is effected in air under a layer of a liquid flux designed for soldering metals with metallic spelters. Also proposed is a copper-tin-titanium soldering agent which, in accordance with the invention, has the following composition, wt.%:
