Featuring a halide- and zinc-free formula with good wetting performance and minimal residue, it enables clean, reliable joints—ideal for demanding applications in medical, aerospace, and microsystem technologies.
Emil Otto introduces EO-M-026, a ready-to-use, high-performance flux specifically designed for soldering and tinning nickel-based alloys, especially nitinol. This innovative, water-based formula is free of zinc, halides, and VOCs (0%) and combines powerful inorganic activators with complex organic additives and wetting agents.
Due to its highly concentrated formulation and robust activator system, it delivers excellent wetting characteristics and ensures minimal residue after processing. The flux supports clean, consistent soldering even on challenging materials like nitinol, which is known for its stable oxide layer that complicates soldering. The flux can be applied flexibly via dosing, dipping, immersion, or selective soldering. Its transparent liquid form is non-flammable, odor-mild, and safe to handle, making it ideal for sensitive applications.
The key characteristics are:
- Available in standard container sizes: 1 L, 5 L, 10 L, 20 L, and 30 L
- Custom volumes available upon request
- Shelf life: 24 months (stored at 5–25°C in sealed original packaging)
- Suitable for long-term industrial use
It unlocks new possibilities for manufacturers using nitinol—an alloy prized for its shape memory and superelastic properties. By simplifying soldering of this difficult material, and enables strong and reliable metallic bonds in mission-critical components. This makes it ideal for industries requiring high process reliability and cleanliness, particularly medical technology (e.g., stents, guide wires, catheters), aerospace (actuators, vibration damping), robotics, microsystems, and precision consumer goods.
“As Nitinol’s oxide layer makes it inherently difficult to solder, EO-M-026 was developed to meet the strict requirements of high-tech industries,” says Markus Geßner, Marketing and Sales Manager at Emil Otto. “Its strong activation power and low-residue profile make it especially effective in medical and aerospace applications where cleanliness and bond reliability are non-negotiable.”
