Suitable for joints with larger clearances.
For joining mild and low alloyed steel, stainless steel, copper alloys, nickel alloys and cast iron.
Operating temperature, up to about 200 °C. // Melting range: 630-730 °C.
Lastek B3034 is cadmium free and applies to the European RoHS guideline and the European cadmium guideline.
Machine parts for food and beverage industry.
Dairy and pharmaceutical industries.
Plumbing, sanitary, piping, refrigeration, air treatment.
Automotive and electrical industry.
Lastek B3034 is also available as coated rod Lastek 3034V.
Joint preparation: optimum clearances 0.05 to 0.20 mm. Preheat the work piece slightly with neutral flame. Preheat the brazing rod slightly and dip it into the flux. The flux will adhere to the rod. Rub the 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.
Powder flux: Lastek 31C (general work) or Lastek 31CH (higher temperatures, e.g. large work pieces in red copper).
Paste flux: Lastek 31CN (general work) or Lastek 31CNB (stainless steel, hard metals and induction brazing).
