CYNEL LEC-LUT0105-500 Estaño para soldar con plomo Sn60Pb40 0,70mm 500g con alma de colofonia

For reliable, consistent solder joints in electronics assembly and repair, the CYNEL LEC-LUT0105-500 delivers a classic Sn60Pb40 alloy in a convenient 500g spool. Its 0.70mm diameter strikes a balance between fine control and efficient solder deposition, while the rosin core flux ensures clean, strong connections on copper, brass, and tinned surfaces. Unlike lead-free alternatives that demand higher temperatures and careful thermal profiling, this leaded wire flows smoothly at a low 183–190°C, reducing the risk of heat damage to sensitive components.

Highlights

• Eutectic Sn60Pb40 composition: 60% tin, 40% lead for a sharp melting point and quick solidification.
• 0.70mm wire diameter ideal for through-hole soldering, wire splicing, and general electronic work.
• Rosin-cored flux (2.5% content) actively cleans oxides and promotes wetting without corrosive residue.
• 500g spool provides ample material for production runs, workshops, and hobby benches.
• Low melting range (183–190°C) protects heat-sensitive parts and speeds up hand soldering.

In daily use

This solder wire is a workhorse for PCB assembly, cable termination, and repair tasks. The rosin flux activates as the wire melts, removing light oxidation and ensuring the solder flows into the joint rather than balling up. Because the alloy is eutectic, it transitions directly from solid to liquid at 183°C, minimizing the pasty phase that can cause disturbed joints. After soldering, the non-corrosive residue can be left in place for many applications, though it may be cleaned with isopropyl alcohol if desired.
