Sn99.3Cu0.7 SW26 solder is the most effective alternative to lead-based solders, offering exceptional performance for both professional and amateur applications. It is a lead-free product with medium activity, containing rosin halide flux.
Produced by Cynel-Unipress in the first smelting of tin and copper, it meets the quality standards specified by the ISO 9453:2014 standard. It is used in lead-free technology, adapting to the requirements of the RoHS directive, which allows its use in a wide range of applications, including the consumer sector.
The composition of the binder is dominated by tin, with copper content in the range of 0.5 - 0.9%. The minimal presence of other elements guarantees that the product is free from impurities. It is characterized by a melting point of 227°C, specific gravity of 7.31 g/cm3, resistivity of 0.126 μΩ•m and thermal conductivity of 66 W/m•K. The tensile strength is 300 kg/cm2 and the elongation at break is 21%. The recommended temperature of the soldering tip is 320 - 360°C, with the possibility of increasing it to 400°C for nickel-plated elements.

SW26 flux, an integral element of this binder, is a halide product based on modified rosin. It is optimal for many industrial and amateur applications, working effectively on most metal surfaces except aluminum and stainless steel. Its markings according to standards are SW26 according to DIN 8511, 1.1.2 according to ISO 9454-1, and ROL1 according to J-STD-004. It contains a standard content of 2.2% ± 0.2% of flux, with the possibility of agreeing other contents, halides at the level of 0.5% and an acid number of 180mg KOH/g. It is non-corrosive and complies with the copper mirror test, confirming its reliability and safety in use. Flux residues do not need to be removed, which makes the soldering process easier and faster.
