Brazing alloys

For capillary brazing, the company produces a wide range of powder brazing alloys that are used in electric engineering, electronics, the tool-making industry, aviation motor-building, the thermal power industry, mechanical engineering, and other fields.

The use of powder brazing alloys reduces the labor intensity of the technical process of brazing, and makes it possible to accurately dispense material, mechanize brazing operations, and introduce radically new structural and engineering solutions.

JSC POLEMA is open to developing partnerships in this field, and to creating and adapting industrial production of new grades and forms of highly effective brazing alloys.

POLEMA powder brazing-ready brazing alloys are classified by groups based on chemical composition and technological properties:
