Abstract
A paste composition for aluminum brazing of the invention contains 40 to 65% by weight of a metal powder for brazing (a), 5 to 35% by weight of a fluoride type flux (b), 1 to 10% by weight of a methacrylic acid ester type polymer (c), and 10 to 40% by weight of an organic solvent (d); and the component (d) is a hydrocarbon type organic solvent having no aromatic ring and no hydroxyl group and the composition is in a paste-like state having a viscosity of 6,000 to 200,000 mPa·s at 23° C. and accordingly, the storage stability and applicability (practically, discharge property and pressure stability by using a dispenser) and brazing property can be improved in good balance.
