LF3135NC Cored Solder Wire
Lead-Free, No-Clean Cored Wire
LF3135NC Cored Solder Wire is manufactured by a long term trusted partner of DKL Metals.
The cored wire uses a high-temperature activator. This ensures perfect soldering even with low flux content. The system provides excellent non-corrosive behaviour. It is a halide containing, resin based no clean solder wire.
High Activation Performance
This wire excels on oxidised components. It is optimised for robotic soldering and high-speed rework.
Wire Gauge & Flux Ratio
Diameters range from 0.5mm to 2.5mm. Choose from 1.4%, 2.2%, or 3.5% flux contents.
Storage & Shelf Life
Store in a clean, dry environment at room temperature. This product has a minimum 5-year shelf life.

LF3135NC Cored Solder Wire FAQ
What are the available alloys and melting points?
+
LF3135NC is available in a wide variety of lead-free alloys:
| Alloy | Composition | Melting Point (°C) |
|---|---|---|
| SN100C | SnCu0.7Ni | 227°C |
| SN96C | SnAg3.8Cu0.7 | 217°C |
| SN97C | SnAg3.0Cu0.5 | 217-220°C |
| BiSn42 | Bi58Sn42 | 138°C (Low Temp) |
| SnAg4 | Sn96Ag4 | 221°C |
| SNSb5 | Sn95Sb5 | 235-240°C |
| SnCu3 | Sn97Cu3 | 227-310°C |
Is LF3135NC suitable for automated soldering?
+
Yes. Balver Zinn specifically recommends this wire for manual, robotic, and repair soldering. The activator has an increased decomposition temperature, which ensures optimum results even with low flux content during high-heat automated processes.
How is the flux classified?
+
The flux is classified as REM1 (EN 61190-1-1) or RoM1 (J-STD-004). It is a halide-containing, rosin-based formulation that provides higher activation for difficult soldering tasks while remaining a true “no-clean” product.
What is the shelf life of this wire?
+
When stored in a clean, dry environment at room temperature, LF3135NC cored solder wires have a minimum shelf life of 5 years.
