Kontakt 1030 Ag is a cadmium-free silver brazing alloy. The special high purity copper and zinc alloy with 30% silver ensures excellent wetting and easy use. Kontakt 1030 Ag is specially designed for maintenance and repair of food and refrigeration equipment. The brazing rod is coated with flux to simplify the working process and ensure a strong and corrosion resistant joint. The working temperature range is from 665 to 755 °C.
Kontakt 1030 Ag is used for manufacturing permanent joints by brazing stainless steel, copper alloys, brass, cast iron and bronze parts. It is possible to join both similar and dissimilar materials.
Application examples – joining and repair of stainless steel and non-ferrous equipment, instruments and fittings in food, pharmaceutical and medical industries, as well as refrigeration, cooling and heating systems, chemical industry and laboratory equipment manufacturing and repair.
