BRAZING FLUXES
BRAZING FLUXES
The purpose of the flux is to remove oxides, resulting from the heating process of the joining faces of the metal and the liquid solder. The choice of flux depends on the brazing material, the binder used and the method of soldering. By operation of the flux solders can freely melt the joining faces of the metal.

Fluxes for silveralloys | ||||
TLS-1 | 550-870 | FH10 | FB3A | Universal white paste flux for use with silver brazing alloys . May be used for bonding stainless steel, brass, bronze and other ferrous and non-ferrous metal alloys. Flux residue is corrosive, water soluble and easy to remove. |
TLS-2 | 570-980 | FH12 | FB3C | Black paste flux with improved activity and a wide range of temperatures. Recommended particularly in the event of rapid spot heating. Used for brazing stainless steel, cemented carbides and other ferrous and non-ferrous metals with silver filler metals. Flux residue is corrosive, water soluble and easy to remove. |
TLS-F | 550-800 | FH10 | FB3A | Universal brown paste flux used with silver and copper-phosphorus alloys. Flux residue is corrosive, water soluble and easy to remove. |
TLS-E | 427-871 | FH10 | FB3A | Universal brown paste flux used with silver and copper-phosphorus alloys. Flux residue is corrosive, water soluble and easy to remove. Ecological flux. |
Fluxes for copper-phosphorusalloys | ||||
TLS-F | 550-800 | FH10 | FB3A | Universal brown paste flux used with copper-phosphorus and silver alloys. Flux residue is corrosive, water soluble and easy to remove. |
TLS-E | 427-871 | FH10 | FB3A | Universal brown paste flux used with silver and copper-phosphorus alloys. Flux residue is corrosive, water soluble and easy to remove. Ecological flux. |
TLP-1 | 550-800 | FH10 | FB3A | Flux in powder form, recommended for brazing ferrous and non-ferrous metals Usually used if the joint dimensions required long heat-up times. Most commonly used for brazing copper and its alloys using copper/phosphorus filler metals and silver alloys with a low content of silver (below 30%). Flux residue is corrosive, water soluble and easy to remove. |
Fluxes for brassalloys | ||||
TLB-1 | 700-950 | FH20 | - | Flux in a paste for brass alloys Flux residue is corrosive and should be removed using warm water. |
TLB-3 | 750-1050 | FH21 | FB3D | Universal paste or powder flux recemmended for brass alloys. Flux residue is corrosive and should be removed using warm water. |
Fluxes for aluminium alloys | ||||
TLA-1 | 520-635 | FL10 | - | Hygroscopic flux for flame brazing. Ideal for brazing aluminium alloy elements with a magnesium content of up to 2.5 %. Flux residue is corrosive, should be removed after brazing. Recommended for Al-Si alloys. |
TLA-2 | 515-630 | FL10 | - | Hygroscopic powder flux for brazing aluminium and its alloys. Recommended for Al-Si alloys. Fluxresidueiscorrosive, should be removedafterbrazing. |
TLA-4N | 420-480 | - | - | Non-hygroscopic powder flux for brazing aluminium and its alloys. Flux residue is not corrosive. |
