Abstract
1,270,864. Soldering. LAKE CHEMICAL CO. 21 Aug., 1969 [2 May, 1969], No. 41816/69. Heading B3R. [Also in Division C7] A stainless steel soldering flux comprises a major proportion of orthophosphoric and/or phosphorous acid and a minor proportion of finely divided Cu and/or Cu salts. The acid may be 70-72% phosphorous acid or 40-115%, preferably 75-105%, orthophosphoric acid. The Cu salts may be the acetate, basic cupric chromate, cupric dichromate copper carbonate, salicylate, cupric phosphite, cupric phosphate and complexes with ammonia or amines in an amount of 1-40% of the acid. The Cu content is 1-10% of the acid content. 20- 60% of optional constituents, e.g. ammonia, organic amines and ammonium phosphate and 2-25% of non-ionic surfactants may be present. Halides, sulphates and nitrates of Cu are preferably absent. The flux may be a solution, a solid or a paste and is used for soldering stainless steel to Cu and its alloys, stainless and non-stainless steels. Conventional Pb-Sn solders are used.
