Hard solder / soft solder

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".

Blockade® braze is a phosphorus-tin-silicon braze for soldering copper and brass with a very low working temperature (650°C). This hard solder can be used as an alternative to the significantly more expensive Ag-55 silver solder (working temperature 630°C). Blockade has good flow properties, the soldering gap fills very quickly and forms an evenly formed groove at the soldering point with a smooth surface. Blockade® brazing solder is suitable for hat soldering copper and copper alloys, such as brass, bronze, gunmetal. You will receive a flux-coated rod from us and do not need any other additives or fluxes. The flux-coated brazing rods are suitable for all flame brazing processes as well as for induction heating and oven brazing. Blockade is used in the refrigeration, air conditioning and electrical industries. We at Bengs Modellbau are now increasingly using brazing solder in our model making workshop. In order to keep shipping costs as low as possible, we cut the brazing rods into 2 equal parts. You will then receive 2 pieces from us with a length of 250 mm. For larger quantities or when sending parcels, you will receive the brazing rods in the original length of 500 mm. Properties flux coated phosphorus-tin-silicon braze blockage Diameter: 2mm  Length: 500mm Phosphor-tin-silicon alloy Working temperature: 650C° No additional flux required Cadmium-free The easiest way to remove the contamination caused by the flux after brazing with the phosphorus-tin-silicon brazing solder blockage is with our Abrasive fleece.

Soft soldering paste for brass, copper, steel and silver steel. The paste is applied thinly to the parts to be tinned and heated with a brazing lamp. For large-area soft soldering, it is optimal to tin- the parts beforehand. For example, we use the paste to pre-tine the cylinder and the mirror when constructing a model steam engine. The tinning paste can also be used optimally as a flux substitute. The soft soldering paste is excellently suitable as corrosion protection for steel parts. Bengs Modellbau uses the zinc paste for steel cylinders with a cooling water jacket. For example in the Flammenfresser Kurfürst. Stirring the paste before use is not necessary! The soft soldering paste may be diluted with water.

High temperature soft solder with a melting point of 250 ° C is suitable for fittings, pipelines and components on steam engines, Stirling engines and flame eaters. The soft solder is filled with a flux that burns without residue when flame brazing (flux residues must be removed in the case of piston soldering !!!). If you need additional flux, you can use normal soft solder flux. Due to the increased melting point of 250 °, it is a good alternative to brazing. However, the high-temperature softening braze can not replace brazing. This product should not be used in the vicinity of the boiler. The use of silver solder is recommended.

Body tin for tinning weld seams, for leveling out dents, dents, unevenness, for adjusting gap dimensions on hood/door edges, body tin has a very large melting range and optimal gap filling. Body tin is often used, especially when restoring vintage cars. Body tin can also be used in model making. If you heat the solder to the working temperature, it has a cake batter-like consistency and can be spread with an oiled wooden spatula. In car body construction, this property is used to compensate for dents or dents. In technical model making, this can be helpful when creating molds or with a special shape (inner radius) for model components. If you use lead-free body tin we recommend this alloy. Sn90Zn7Cu3 is always our first choice. Application body tin  First, the component on which the body tin is to be applied must be treated with tinning paste nt become. While the soldering point is still warm, wipe it off with a wet cloth so that the tinning paste has a silvery shine. Now both the component and the body tin are brought evenly to working temperature. As soon as the solder begins to become soft, it is pressed onto the component with light pressure so that small piles form. As soon as enough tin has been applied to the area, the entire material is heated gently until it has reached a cake batter-like consistency. Now it can be spread with a wooden spatula soaked in linseed oil, for example. Finally, the excess material is removed with a coarse file until the desired shape is achieved. If you use lead-free body tin we recommend this alloy. Sn90Zn7Cu3 is always our first choice. Technical data per rod Weight per bar: approx. 225 grams Dimensions approx. 9 x 10 x 400 mm pressed bar FELDER rod plumb bob according to DIN EN ISO 9453 Lead-free Alloy: Sn90Zn7Cu3 Melting range: 200-254°C

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
