Lastek B3045 V

Flux coated cadmium free silver brazing, general purpose

Flux coated, cadmium free silver alloy, high silver content, for capillary brazing. Excellent flowing characteristics and capillarity. Low melting point, for general use.

For joining copper and copper alloys, nickel and nickel alloys, malleable cast iron and steel. Thanks to the low melting point very suitable for brazing of dissimilar metals. High corrosion resistance and seawater resistant.

Operating temperature, up to about 200 °C. // Melting range: 640-680 °C. (working temperature 670 °C).

Lastek B3045V is cadmium free and applies to the European RoHS guideline and the European cadmium guideline.

Specifications & Usage


Machine parts for food, beverage, dairy and pharmaceutical industries.

Plumbing, piping, air treatment and conditioning.

Automotive and electrical and electronics industry.



Joint preparation: optimum clearances 0.05 to 0.15 mm.

Preheat the work piece slightly with neutral flame.

Rub the coated rod along the joint to apply the flux. As soon as the flux is flowing, melt the rod. Continue heating until the alloy flows into the entire joint by capillarity.

Cool down and remove flux residues by brushing with hot water.
