Tin coil 2.5 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 handled separately or not required.

SN100C® is a eutectic tin-copper alloy stabilized with nickel and enhanced with germanium to permanently reduce solder oxidation. This combination ensures a stable soldering process, reduced dross formation, and high-reliability, aesthetically pleasing solder joints.

World-renowned lead-free solder alloy

SN100C® was developed as a cost-effective alternative to silver-containing 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 consistent solder joints, while germanium reduces solder pot oxidation and contributes 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 delivery is desired.

Typical applications include:

• Wire tinning
• Dip soldering
• Solder pot maintenance
• Industrial soldering processes
• Electronics production
• Industrial electronics
• Automotive electronics
• Special applications with separate flux delivery

The large 4 kg coil ensures long operating time and makes the product suitable for continuous production environments.

Flexible diameter for production and maintenance

With a diameter of 2.5 mm, this variant offers a good balance between precise dosing and efficient solder metal delivery. This makes the product suitable for both production tasks and maintenance of soldering equipment, where high control over material delivery is desired.

The solid wire also ensures maximum flexibility in processes where flux is handled separately.
