CYNEL CÍNOVÁ ROLKA 2,5 mm 250 g Sn60Pb40 spájkovací drôt s kolofóniovým jadrom

With a melting point of just 183–190°C, this Sn60Pb40 solder wire flows smoothly and solidifies fast, making it a reliable choice for electronics repair and general-purpose soldering. The 2.5 mm diameter and 250 g spool provide a practical balance between heat control and material supply for both hobbyists and professionals.

Overview

The CYNEL TIN SPOOL is a rosin-core solder wire composed of 60% tin and 40% lead. Its 2.5% flux content cleans surfaces during soldering, leaving a non-corrosive, non-conductive residue that protects joints without compromising electrical performance. The wire is wound on a plastic spool, ensuring tangle-free dispensing and easy storage.

What stands out

• Sn60Pb40 alloy offers a low melting range for efficient work on heat-sensitive components.
• Rosin core flux removes oxides and improves wetting, resulting in strong, shiny joints.
• Non-corrosive, non-conductive residue eliminates the need for post-solder cleaning in most applications.
• Compliant with ISO 9453 alloy standards, ensuring consistent quality and performance.
• Plastic spool protects the wire from oxidation and mechanical damage during storage.
