Flux coated, cadmium free silver alloy, moderate silver content. Good flowing characteristics and sufficient capillarity, so suitable for joints with large clearances.
For joining mild and low alloyed steel, stainless steel, copper alloys, nickel alloys.
Operating temperature, up to about 300 °C. // Melting range: 680-760 °C.
Lastek B3025V is cadmium free and applies to the European RoHS guideline and the European cadmium guideline.
Machine parts for food and beverage industry.
Mechanical and electrical industry.
Heat exchangers.
Joint preparation: optimum clearances 0.05 to 0.20 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.
