| Material: | Elkaflux Powder |
| Application: | This is a general purpose flux. It is highly active and can be used on most metals capable of being brazed with silver-bearing brazing alloys. With a working range of 580 - 800oC it is suitable for use with the lowest melting point silver brazing alloys and has sufficient life at temperature for most brazing operations. |
| Elkaflux powder can be used to braze stainless steel provided that the heating cycle is not too long and that the brazing temperature is below 700oC. It has excellent hot rodding characteristics and can be readily mixed into a creamy paste by addition of water. | |
| Working Practice: | Flux Application |
| The best way to apply a flux is to paint it onto the joint as a paste. It is common to see operators heating the rod end and dipping it into the flux, and then applying both to the joint. This 'hot rodding' technique has the disadvantages that the flux does not protect the joint during the heating cycle, and that the limited amount of flux applied does not prevent oxidation of the parent metals in the vicinity of the joint. Alloy penetration into the capillary gap is also restricted. | |
| A flux powder should be mixed to a double cream consistency with water and a few drops of detergent. It should be applied to the joint by means of a paint brush. Too much flux will rarely result in a bad joint, but too little flux will invariably give joints of poor quality. | |
| Removal of Flux Residues | |
| Elkaflux residues can be quite simply removed by soaking in hot water, provided they are not in a burnt and blackened condition. Complete flux residue removal is usually possible within 10 to 15 minutes of soaking in water with a temperature of 60oC or above. After soaking, the joints should be scrubbed under running water to ensure complete cleanliness. | |
| Acid pickling is not effective in removing flux unless the residues are in a burnt and blackened condition. If pickling is necessary it should be carried out after the flux residue removal operation. | |
