Solder Wire CYNEL Cyna 1.5mm 1000g Sn60Pb40 Flux‑cored soldering alloy

CYNEL Cyna 1.5mm solder wire on a 1000 g spool is a flux‑cored Sn60Pb40 alloy intended for general electronic and electrical soldering. The 60/40 tin‑lead composition provides a controlled melting range and reliable wetting on common copper, brass and tinned surfaces. The 1.5 mm diameter and large spool size make this wire suitable for routine through‑hole work, hand soldering, repair tasks and small assembly operations where a traditional tin‑lead solder is specified.

Advantages

The flux‑cored construction integrates flux inside the wire, reducing the need for separate flux application and helping to produce consistent joints during manual soldering. The Sn60Pb40 alloy offers good flow characteristics and solid mechanical strength for general electrical connections. A 1.5 mm diameter balances ease of feed and fast heat transfer for medium‑sized joints, while the 1000 g spool reduces spool changes in workshop or production settings.

Suitable for

• Through‑hole PCB soldering and component replacement
• Repair and rework of connectors, wires and terminals
• General electrical and metal joint soldering where Sn60Pb40 is specified
• Hobby electronics and small‑scale assembly requiring a flux‑cored tin‑lead alloy

Key specifications

• Alloy composition: tin/lead 60/40 (Sn60Pb40)
• Wire diameter: 1.5 mm
• Product form: flux‑cored solder wire
• Spool weight: 1000 g
• Typical applications: electronic and electrical soldering, metal joints

How to use

Prepare surfaces by cleaning to remove oxidation, grease or contaminants for optimal wetting. Heat the joint with an appropriate soldering iron or soldering tool until the base metals reach soldering temperature, then apply the flux‑cored wire to the heated area, allowing the solder to flow and form a smooth fillet. Avoid overheating and ensure proper ventilation when soldering. After cooling, inspect the joint for good wetting and remove any residual flux if required by the application.

Usage recommendations

Use an iron temperature suitable for Sn60Pb40 alloys (typically in the range recommended for leaded solders), select tip sizes that match joint dimensions, and work in a well‑ventilated area. For electronics, avoid excessive solder application that can create bridges; for mechanical joints, ensure adequate solder penetration and fillet formation. Follow local safety and disposal regulations for leaded solder and flux residues.
