CYNEL Sn60Pb40 solder tin wire is an alloy wire composed of 60% tin and 40% lead, supplied in a 1 kg spool with a 0.56 mm diameter. It is formulated for general-purpose soldering of through-hole and surface-mounted components in electronics and electrical repairs where a Sn60Pb40 composition is appropriate. The alloy balances melting characteristics and mechanical strength to provide reliable wetting, consistent flow, and durable joints for repair, prototyping, and small-scale assembly work.
Advantages
The Sn60Pb40 composition offers a predictable melting range and good solderability on common component leads and PCB pads. A 0.56 mm diameter wire delivers controlled solder feed for manual soldering and rework, reducing excess solder and enabling accurate joint formation. The 1 kg spool reduces the need for frequent replenishment in workshop settings, while the alloy’s mechanical properties help maintain joint integrity under typical handling and thermal cycling conditions.
Suitable for
- Through-hole soldering of components such as resistors, capacitors and connectors
- Manual rework and repair of electronic assemblies
- Prototyping and small-batch electronics assembly
- General electrical connections and wire splicing where leaded solder is acceptable
Key specifications
- Alloy composition: 60% tin, 40% lead
- Wire diameter: 0.56 mm
- Package weight: 1 kg spool
- Form: solid solder wire suitable for manual soldering
How to use
Prepare the workpieces by cleaning pads, leads, and contact surfaces to remove oxides, grease, or contaminants. Heat the joint evenly with a suitably sized soldering iron tip and apply the solder wire to the heated area, allowing the molten solder to wet the surfaces and form a smooth fillet. Withdraw heat once the solder has flowed and formed a proper connection; avoid moving the joint until the solder has solidified. Use appropriate flux if the wire does not include a core flux, and observe recommended soldering temperatures for Sn60Pb40 alloys to ensure reliable joints.
Usage recommendations
Use adequate ventilation or local fume extraction when soldering lead-containing alloys. Comply with local regulations and workplace safety guidelines regarding the handling and disposal of leaded solder and residues. Select a soldering iron temperature suitable for Sn60Pb40 to minimise thermal stress on components while ensuring sufficient wetting and flow.
