Tin solder wire 3.0 mm Sn63Pb37SW – 4 kg reel (WBZ BaTiLoy)
Sn63Pb37SW from Balver Zinn is a classic lead-containing solder alloy developed for professional soldering processes where high process stability, excellent wetting properties, and consistent soldering results are crucial. This solid solder wire is supplied on a 4 kg reel with a diameter of 3.0 mm and is suitable for wave soldering, selective soldering, dip soldering, and tinning.
The eutectic Sn63Pb37 alloy has been the standard in electronics manufacturing for decades and is still used in many industrial applications where lead-containing processes are permitted or required.
Sn63Pb37 – the electronics industry's classic solder alloy
Sn63Pb37 consists of 63% tin and 37% lead and is known for its precise melting point of 183 °C. As the alloy is eutectic, it transitions directly from solid to liquid without a plastic transition zone.
This offers several significant advantages:
• Rapid solidification
• Low risk of cold solder joints
• Excellent wetting
• High process stability
• Uniform solder joints
• Proven reliability
The alloy is still widely used in electronics production, service, and maintenance.
Suitable for tinning and industrial soldering processes
The solid 3.0 mm solder wire is particularly suitable for:
• Wire tinning
• Dip soldering
• Wave soldering
• Selective soldering
• Solder pot maintenance
• Electronics manufacturing
• Industrial electronics
• Automotive electronics
The large 4 kg reel makes the product ideal for production environments with high material consumption.
High solder quality and attractive solder joints
Sn63Pb37SW is known for delivering strong and uniform solder joints with an attractive solder appearance.
Advantages include:
• Shiny solder points
• Good through-hole fill
• Reduced risk of solder bridges
• High reproducibility
• Stable process throughout long production runs
This makes the alloy a reliable choice for productions with high demands for quality and process control.
Ideal for production and maintenance
