Tin coil 3.0 mm SN100C® – SnCu0.7Ni – 4 kg coil (WBZ TripleX:2015)
SN100C® from Balver Zinn is one of the world's most widely used lead-free solder alloys, developed for companies seeking high process stability, low operating costs, and consistent solder quality. This variant is supplied as solid solder wire without flux on a 4 kg coil and is suitable for industrial soldering processes where flux is managed separately or not required.
SN100C® is a eutectic tin-copper alloy stabilized with nickel and enhanced with germanium to permanently reduce oxidation of the solder. This combination results in a stable soldering process, reduced dross formation, and excellent, highly reliable solder joints.
World-renowned lead-free solder alloy
SN100C® was developed as a cost-effective alternative to silver-bearing lead-free alloys and is now used by electronics manufacturers worldwide. The alloy is known for its stable process behavior and excellent soldering properties in standard electronics, industrial electronics, and advanced electronics applications.
The nickel-stabilized structure helps ensure uniform solder joints, while germanium reduces oxidation of the solder bath, contributing to lower material consumption.
Solid solder wire for industrial processes
This variant is supplied as solid solder wire without flux and is particularly suitable for production environments where full control over both solder metal and flux application is desired.
Typical applications include:
• Wire tinning
• Dip soldering
• Solder pot maintenance
• Industrial soldering processes
• Electronics manufacturing
• Industrial electronics
• Automotive electronics
• Special applications with separate flux supply
The large 4 kg coil ensures long operating times and makes the product suitable for continuous production environments.
Suitable for larger solder points and high material input
The robust 3.0 mm wire diameter makes the product suitable for tasks requiring large amounts of solder metal to be applied quickly and controllably. This makes the solder wire particularly interesting for industrial processes, current-carrying connections, and other applications with high thermal mass.
