Nickel and Alloys

Nickel and Alloys

Nickel provides corrosion resistance, mechanical support, and electrical conductivity to AEM applications. This metal’s characteristics ensure durability in alkaline environments over the electrolyzer’s lifespan. Our nickel PTL is suitable for the high pH values of AEM technology. And it is available in thicknesses up to 1mm, depending on design constraints. We also offer alloys (Inconel, HR) suited for AEM applications given their high corrosion resistance and good electrical properties.

When it comes to AEM, managing scalability, accessibility, and expenses are key. Because nickel is an abundant metal, it contributes to operational efficiency and performance. Depending on the application, this metal is more prevalent than stainless steel. In all, nickel PTLs serve as a sustainable approach to the production of hydrogen.

Sintered metal fiber media have pore sizes in the µm-range.

  • Compared to sintered metal powder, higher porosity, and thus permeability, can be achieved at similar pore size.
  • Compared to metal foam, sintered metal fiber media enable a stepwise reduction in pore size and corresponding increase in surface area.

All your Questions Answered

  1. Are nickel alloys available?

    arrow

    Yes, we offer Inconel and Hastalloy (HR) alloys for enhanced performance.

  2. Does Bekaert offer Nickel foam and/or powder?

    arrow

    Currently we do not offer nickel (Ni) foam or nickel (Ni) powder.

  3. What are the tolerances on dimensions, length, width and thickness?

    arrow

    The standard tolerances which are applicable to the dimensions of our sample materials: ± 4mm.

    For commercial projects, we have custom cutting technologies with tolerances of ± 0,5 mm and a thickness tolerance of ± 10%.

  4. What is the grade of the materials being used?

    arrow

    Grade 200

  5. Why is nickel used in AEM electrolysis?

    arrow

    Nickel is corrosion-resistant in alkaline environments and offers excellent conductivity at a lower cost than noble metals. 

  6. What is the new name of the materials I have ordered in the past?
