It can be moderately diluted with distilled water or ethyl alcohol.

Applications
This flux is mainly used with AluTin 51 alloys.
aluminum compounds (Si + Mg < up to 2 %) or for the dissimilar connection of copper/aluminum.

Processing instructions
Preparation

• If necessary, clean the joint surfaces and round off sharp edges.
• Degrease the parts with a suitable solvent.
• Coat all connecting parts with AluTin 51 L flux.
• Bring the parts into their final position.
• Set the welding torch so that you obtain a gentle, slightly carburizing flame.
• Heat the parts to be joined indirectly and evenly to the joining temperature.
• Do notoverheat the flux to avoid damage and do not hold the flame directly on the flux.
• Hold the end of the filler alloy rod to the joint.
• The filler alloy metal will spread to the hottest areas of the surfaces to be joined.
• Melt the filler alloy metal until the joint is completely filled.

Cleaning

• The residues of the AluTin 51 flux are water-soluble.
• They are usually removed by washing in hot water.
