High-temperature soldering flux "Bura"
Designed to remove oxides from the surface for soldering, improve the spreading of liquid solder when brazing carbon steels, cast iron, copper and its alloys with copper-zinc and silver solders. When working with flux, it is important to observe safety precautions: the substance must be stored in places inaccessible to children. The "Bura" flux guarantees good flowability of the solder and high strength joints.
Features: High-temperature flux is used for soldering parts or surfaces in the temperature range from 800 to 1150 ° C. Popular for soldering jewelry made of gold, silver, cupronickel. It is a white (light gray) powder that dissolves well in water and, when heated, turns into a glass mass, which protects the soldering zone. Promotes high-quality fusion of common metals with noble ones by means of gas-flame heating. To avoid corrosion, after soldering, rinse the surface with hot water using a brush or brush. net weight: 300 g; • country of manufacture: Russia.
