AlumWeld Blue 25 g


Flux for torch soldering using AlumWeld LQ and AlumWeld CL.

AlumWeld Blue is an active flux which facilitates aluminium soldering. It significantly improves the wettability of soldered parts and the flow of the filler metal. The connections should be made with AlumWeld CL or LQ alloy. Residues after soldering should be rinsed with warm water. A pack contains 25 g of flux. This is enough for approximately two packs of the solder.

Soldered metals:

  • aluminium and its alloys,
  • copper,
  • brass,
  • bronze,
  • stainless steel,
  • galvanised and plain steel.
