Main Features

• Specialized for hard-to-solder metals: suitable for stainless steel, nickel alloys, galvanized metals, mild steel, and iron.
• Useful for battery work: can be used with lithium-ion battery terminals and coin cell batteries when proper heat control is followed.
• Suitable for neodymium magnets: helps soldering on magnet surfaces when used carefully with the right soldering tip.
• Non-halogen activators: formulated with non-halogen and halide-free activators.
• Improves wetting: helps the solder spread better on difficult surfaces.
• Oxidation removal: supports surface cleaning before the solder bond forms.
• Cleanable residue: post-solder residue can be cleaned with distilled water, alcohol, or a suitable thinner.
• Controlled application: supplied in a compact 15mL plastic dropper bottle.

Recommended Uses

• Soldering stainless steel plates and wires.
• Soldering nickel alloys and nickel-plated surfaces.
• Soldering galvanized metals, mild steel, and iron.
• Soldering lithium-ion battery terminals with careful heat control.
• Soldering coin cell or watch battery terminals after surface preparation.
• Soldering neodymium magnets using a suitable tip and controlled heat.
• Automotive restoration and old radiator repair when using suitable high-power soldering tools.
• Quick cleaning and fixing of oxidized soldering iron tips.

How to Use

1. Clean the target surface from dust, grease, oxide, and any old residue.
2. Apply a very small amount of flux to the soldering area only.
3. Use a suitable soldering iron tip for the size of the target area.
4. Use suitable soldering iron power according to the metal size and heat required.
5. For larger metal parts, a higher wattage soldering iron may be required.
6. Clean the soldering iron tip during work using a wet soldering sponge.
7. After soldering, clean the residue using distilled water, alcohol, or suitable thinner.

Important Notes

• When soldering the negative terminal of a coin cell battery, sanding and smoothing the surface is recommended.
• Batteries can be damaged if exposed to high heat for too long.
• For neodymium magnets, a copper soldering tip is recommended.
• For radiator repair, a high-wattage soldering iron of at least 200W is recommended.
• Not suitable for aluminium soldering.
• Not suitable for electronic PCB soldering.
• Not suitable for dip soldering or wave soldering.
• Not suitable for fusion welding or flame welding.

Safety Precautions

• Use in a well-ventilated area.
• Do not breathe soldering fumes.
• Close the bottle tightly after use.
• Keep away from children.
• If the liquid touches eyes, wounds, or irritated skin, rinse with enough water and seek professional advice if needed.

Package Includes

• 1 × Acti Soldering Liquid Flux for Nickel & Stainless 15mL dropper bottle

Micro Ohm Quality Note

This product is listed with clear usage notes to help technicians, makers, and workshop users choose the correct flux for the correct material. For sensitive or heat-sensitive parts, always test on a small area first and avoid long heat exposure.
