Solder Wire Topex 60% Sn, 1.5 mm, 100 g - leaded tin solder

Leaded solder wire Topex with 60% tin (Sn) content, 1.5 mm diameter and 100 g weight is a flux-core alloy designed for general electronics and electrical soldering. The tin-rich composition provides good wetting and mechanical strength for typical solder joints on circuit boards, component leads and small metal fittings. The 1.5 mm diameter balances easy feed and controlled solder flow for repair tasks and hobby applications when used with standard soldering irons.

Advantages

This Topex solder wire combines a 60% tin content with a flux core to enable consistent solder flow and reliable wetting on copper and common electronic metals. The 1.5 mm diameter is suitable for both fine and medium joints, offering a compromise between rapid heat transfer and precise application. Packaged as a 100 g spool, it provides a manageable quantity for repair, prototyping and small production runs while keeping storage and handling convenient.

Suitable for

• Repairing and soldering electronic circuit boards and through-hole components
• Joining wires, leads and connectors in electrical assemblies
• Hobby electronics, DIY projects and small-scale prototyping
• Soldering small metal parts where a tin-rich leaded alloy is acceptable

Key specifications

• Alloy composition: leaded tin solder with 60% tin content
• Diameter: 1.5 mm
• Net weight: 100 g
• Flux type: flux-core (internal flux)
• Form: wire on a spool for manual soldering

How to use

Use with a standard soldering iron appropriate for electronics work. Prepare surfaces by cleaning oxidation and contaminants to ensure good wetting. Heat the joint with the iron tip, apply the solder wire to the heated area rather than direct contact with the iron tip, and allow the solder to flow and cover the joint. Remove heat and let the joint cool without disturbance to form a shiny, solid connection. Follow appropriate ventilation and cleaning procedures to remove residual flux after soldering if required.

Usage recommendations

Use suitable personal protective equipment and work in a well-ventilated area. This product contains lead; avoid use on items intended for food contact and comply with local regulations regarding leaded solders. For best results on delicate components, use temperature-controlled soldering irons and appropriate tip sizes to prevent heat damage.
