WARNING: This product contains lead. It is sold exclusively to businesses and professional users. The product is not intended for sale to consumers. Purchase is available only to business customers.

Cynel Sn60Pb40 soldering bar 7 × 7 × 322 mm is a monolithic leaded solder alloy intended for professional soft-soldering processes. The alloy contains approximately 60% tin and 40% lead, providing suitable soldering properties and durable joints in properly selected industrial and workshop applications.

The solder may be used in electronics, electrical engineering, sheet-metal work and roofing applications where compliance with RoHS lead restrictions is not required or where an applicable exemption permits the use of lead.

Applications

• professional soft soldering,
• electronics and electrical engineering,
• manufacture and repair of standard devices and components,
• soldering components with tin and tin-lead coatings,
• professional sheet-metal and roofing work,
• industrial processes in which the use of leaded solder alloys is permitted.

Properties

• solder alloy in bar form,
• monolithic solder without a flux core,
• Sn60Pb40 alloy composition,
• approximately 60% tin and 40% lead,
• melting range of 183–190°C,
• designed for soft soldering,
• intended exclusively for professional use.

Technical data

Directions for use

Thoroughly clean the surfaces to be soldered, removing dirt, grease, oxides and residues from previous processes. As the bar is a monolithic solder alloy without a flux core, a separate flux suitable for the materials and soldering technology must be used.

Heat and apply the solder in accordance with the process parameters established for the specific material, flux and joint type. Do not overheat the alloy and avoid uncontrolled generation of fumes and dust.

Restrictions on use

The Sn60Pb40 alloy contains lead. Before using it in electrical or electronic equipment, verify whether the product is subject to RoHS restrictions. Use is permitted only in processes where lead is legally allowed or covered by an applicable exemption.

Safety information

The product contains lead and may damage fertility, the unborn child and organs through prolonged or repeated exposure. Read the current safety data sheet before use.

Ensure effective ventilation, avoid breathing fumes, dust and vapours, and wear suitable gloves, protective clothing and eye protection. Do not eat, drink or smoke while soldering. Wash hands thoroughly after completing the work.

Storage

Store at room temperature in a dry place, away from food and out of reach of unauthorised persons. Protect against contamination and moisture.
