Solder Wire CYNEL Cyna 1.2 mm 500 g Sn60Pb40 — Leaded Solder Alloy

Solder Wire CYNEL Cyna 1.2 mm 500 g Sn60Pb40 — Leaded Solder Alloy is a tin–lead solder wire formulated for general electronics and electrical soldering. The alloy composition of approximately 60% tin and 40% lead provides a balance of melting temperature and mechanical strength suitable for through-hole assembly, hand soldering, repair work and component replacement. Supplied on a 500 g spool with a 1.2 mm diameter, this solder wire is intended for use with appropriate flux and soldering irons or stations in applications where a leaded alloy is specified.

Advantages

The Sn60Pb40 composition delivers reliable wetting, consistent solder flow and good joint formation on common electronic metals such as copper and tinned surfaces. The 1.2 mm diameter offers easy feed and controlled solder volume for hand-soldering and rework tasks, while the 500 g spool reduces the need for frequent reel changes in a workshop environment. This product is compatible with standard soldering irons and pot soldering processes when used with the correct flux and temperature settings.

Suitable for

• Through-hole electronic assembly and manual soldering
• Repair and rework of circuit boards and wire terminations
• Electrical connections and general-purpose solder joints
• Hobby electronics and prototyping where leaded solder is acceptable

Key specifications

• Alloy composition: approximately 60% tin (Sn) and 40% lead (Pb)
• Wire diameter: 1.2 mm
• Spool weight: 500 g
• Form: solid solder wire on spool
• Recommended use: manual soldering, through-hole assembly, rework

How to use

Use with an appropriate flux for electronic soldering and a soldering iron or station set to the temperature range suitable for Sn60Pb40 alloy. Clean surfaces to be soldered, apply flux where necessary, heat the joint evenly and feed solder until the joint fills properly. Allow the joint to cool without movement to form a solid connection. Observe safe handling practices for leaded solder and avoid inhaling fumes; use local exhaust ventilation or fume extraction while soldering.

Usage recommendations

Store the solder wire in a dry environment to avoid oxidation on the spool. For best results, match iron temperature to the alloy's melting behavior, typically higher than lead-free solders, and use rosin-based or appropriate electronic flux. Dispose of any waste in accordance with local regulations for materials containing lead.
