We have silver braided bars with a silver content of 55% (L-Ag55) with a length of 500mm. Because of the relatively low melting point of this silver braze, the model builder in the field of technical model building is almost exclusively concerned. The working temperature of this hard solder is 630 ° C. The silver as an alloying component in the solder does not only reduce the working temperature, but also improves the flow properties. Furthermore, silver has the positive property of combining well with other metals. For brazing brass and steel, silver solder flux is essential. The low working temperature of the silver solder bars allows the thermal load to be as low as possible for the processed material. It is important not to heat the workpieces too much, especially in the case of brass. In combination with our silver solder flux you achieve with these silver solder always optimal results. The silver braided bars can be purchased from us in the shop in 2 different diameters. For fine soldering as it often happens in technical model construction we recommend the 1mm rods. The 1mm silver braided bars are easy to carry with the hand and can be easily melted with small burners. For larger parts we prefer the 1.5 mm silver solder bars. With these rods you get faster material to the soldering point if needed. What can be brazed?The following materials can be combined with silver solder: brass, copper, gunmetal, gray cast iron, rusting steels and stainless steel. A combination of the materials among each other is easily possible with this silver braze solder. If the material is not known to you, it is always recommended to solder a piece to the sample beforehand. This allows you to determine whether the materials can be combined with the silver braze.Instructions Brazing with silver solder If you have never worked on silver solder and you are not sure how the exact solder brazing procedure is with silver solder, we can help you before you buy the silver solder. We have created a guide for you in our Bengs Modellbaumagazin on the topic "Brazing with silver solder". Here you can find out what you need and have to consider if you want to solder 2 components with silver solder. Tip: Flux residues and discoloration of the material can be optimally eliminated with our satin brushes or abrasive fleece!Characteristics of the silver solder bars500 mm long. 1mm or 1.5mm diameter Silver solder bars L-Ag55 (55% silver) Working temperature 630 ° C Bengs Modellbau has used this silver solder bars for years.  

Ready-to-use and dosing silver solder paste, 56% silver content (L-Ag55) with the working temperature 650 ° C. The silver solder paste is suitable for fine brazing. The hard solder paste is suitable for creating almost invisible soldering seams, even in inaccessible places. With our silver soldering paste, there are virtually no solder residues at the soldering point, which must be labored. No flux required. Dried silver soldering paste is made ready for use again with a few drops of water. Mix thoroughly before removing. Typical application examples for the silver soldering paste are: Apparatus and equipment for the food industry silver contacts Bronze and brass fittings Modelling piping Heat and cooling technology Fashion Jewelry glasses manufacturing Precision Engineering !!! The silver soldering paste is also suitable for kiln soldering (furnace should have a working temperature of at least 680 ° C) !!! Contents 10 g Here you will find a tutorial on how to braze with silver solder paste.

The center punch set consists of 25 center punches made of hardened steel. The center punches are suitable for transferring holes from one component to another. To do this, a centering center punch is inserted either into the hole of an existing component or into the hole of a template and transferred to the second part. The center punch set is suitable for use in mechanical engineering, steel construction, crafts and hobbies. The grain diameters increase by 0.5mm from 1mm to 13mm. The actual dimensions of the center punches are 0.05mm below standard dimensions. All 25 center punches are 120mm long. The center punches are delivered with a clear metal stand. Centering center punch set (25 pieces) from 1mm to 13mm 0.5mm increments

When brazing, fluxes have the task of loosening and removing the oxide layers present on the soldering surfaces and preventing them from forming again during soldering. The flux is adjusted to the working temperature of our Silver hard solder matched. Before use, the flux for silver solder should be stirred well. Using the brush in the bottle, a thin layer can be applied to the component to be soldered. You can find detailed instructions in our model making magazine (Hard soldering with silver solder instructions). If the silver brazing flux has dried out, you can make it liquid again with distilled water. Brazing with silver solder rods without flux is not possible. When the flux is heated with the burner, the water it contains first evaporates. This can be seen in the final formation of small bubbles. When the component is heated further with the flux and the working temperature is reached, the flux paste begins to melt and becomes transparent. Now the moment has come where the silver solder can be added. The effective range of the flux for silver solder is between 500°C and 800°C. The flux is suitable for brazing copper, brass, gunmetal, steel and stainless steel. Tip: Flux residues and discoloration of the material can be optimally removed with our Satin brushes or remove with abrasive fleece. You can get the flux for silver solder from us in the packaging sizes: 50g. Bottle with brush 100g.Bottle without brush
