Lastek B3055 V

Flux coated cadmium free silver brazing, low temperature, high capillary

Flux coated, cadmium free silver alloy with high silver content, for capillary brazing. Low melting point, exceptional flowing and high capillarity. For joining stainless steel, copper alloys, nickel alloys, cast iron and steel.

High corrosion resistance, seawater resistant, outstanding flowing and wetting properties. Good colour match with stainless steel.

Operating temperature, up to about 200 °C. // Melting range: 630 – 660 °C. (working temperature 650 °C).

Lastek B3055V is cadmium free and applies to the European RoHS guideline and the European cadmium guideline.

Specifications & Usage


Piping for gas, water, lubricants and pressure.

Machine parts, electrical contacts, refrigeration, plumbing, air conditioning.

Food, beverage and dairy industry, pharmaceutical industry, cookware and cutlery.


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.
