Solder Wire Mojeledy Cyna 2.00 mm 100 g Sn60Pb40 flux-cored (2.5% flux)

Mojeledy Cyna solder wire with a 2.00 mm diameter and a 100 g spool is an alloyed Sn60Pb40 flux-cored wire containing 2.5% rosin flux. It is intended for general electronics and electrical soldering applications where a lead–tin solder is specified. The combination of 60% tin and 40% lead provides a eutectic-approaching composition that promotes consistent melting behavior and reliable joint formation for through-hole components and many repair and assembly tasks.

Advantages

This solder wire offers stable wetting properties and good flow on copper and common PCB finishes, helping to form mechanically sound and electrically conductive joints. The 2.5% flux core aids oxide removal during soldering, reducing the need for additional flux for routine tasks. The 2.00 mm diameter and 100 g spool format make it convenient for workshop, repair, and hobby use where larger bead volume and longer continuous feed are beneficial.

Suitable for

• Through-hole electronic assembly and repair
• Electrical connections on wires and terminals
• Hobbyist and DIY soldering projects
• General-purpose soldering where Sn60Pb40 alloy is acceptable

Key specifications

• Alloy composition: 60% tin (Sn), 40% lead (Pb)
• Flux content: 2.5% flux core (rosin-based)
• Diameter: 2.00 mm
• Net weight: 100 g spool
• Typical melting behavior: near-eutectic alloy for predictable melting

How to use

Use appropriate soldering iron tips and temperatures suited to Sn60Pb40 solder, typically higher than pure tin solders; adjust the temperature to achieve smooth wetting without overheating sensitive components. Clean contact surfaces before soldering to improve joint quality, and feed the wire to the heated joint so the flux activates and the solder flows around the parts being joined. After soldering, allow joints to cool naturally and inspect for shiny, continuous fillets; remove any flux residues if required by the application or cleanliness standards.

Usage recommendations

For safety and best results, work in a well-ventilated area and use appropriate fume extraction when soldering leaded alloys. Use personal protective equipment as needed, avoid contaminating electronic contacts with unnecessary residues, and follow local regulations for handling and disposal of lead-containing materials.
