Soldering Wire Topex 60% Sn, 1.5 mm Ø, 100 g spool

Topex soldering wire with 60% tin content in a 1.5 mm diameter provides a reliable filler material for manual and occasional workshop soldering. Supplied on a 100 g spool, the alloy formulation is designed for use on electronic joints, electrical connections and general metalwork where a reduced-lead or high-tin composition is preferred. The wire feeds smoothly from the spool and is compatible with standard soldering irons and temperature-controlled stations suitable for hobbyist and light professional tasks.

Advantages

This soldering wire combines a high-tin composition with a medium 1.5 mm diameter to enable good wetting and secure joints on copper, brass and many common metals used in electronics and small repairs. The spool format keeps the wire tidy and reduces tangling during work. Compatibility with standard soldering irons and stations simplifies use without the need for specialized equipment.

Suitable for

• Electronic soldering of wires, pads and component leads
• Repair and maintenance of small electrical connections and connectors
• General metalwork and light plumbing tasks that accept tin-based solder
• Hobbyist projects, DIY electronics and occasional workshop use

Key specifications

• Alloy composition: 60% tin (Sn) with balance of other solder metals
• Wire diameter: 1.5 mm
• Spool weight: 100 g
• Format: solid continuous wire on spool for manual feed
• Compatibility: standard soldering irons and temperature-controlled stations

How to use

Prepare surfaces by cleaning and, if necessary, applying a suitable flux compatible with the alloy. Heat the joint with a soldering iron to the appropriate temperature for the metal and wire diameter, then apply the solder wire to the heated area—not directly to the iron tip—to ensure proper melting and flow. Allow joints to cool undisturbed to form a solid connection. Store the spool in a dry environment to prevent contamination and oxidation.

Usage recommendations

Use a flux that matches the solder alloy and the materials being joined, and select an iron temperature that melts the 1.5 mm wire cleanly without overheating components. For electronic work, avoid excessive heating of sensitive components and clean residues after soldering if necessary.
