At Nikken Ras Kogyo, we manufacture high-quality power supply materials and electrode substrates in the hydrogen and fuel cell fields. As solid polymer-type water electrolysis devices and alkaline water electrolysis devices in the hydrogen and fuel cell sectors are expected to become larger and mass-produced in the future, the power supply materials (titanium ras) and electrode substrates (nickel ras) incorporated into them will also increase in size. We have introduced a leveling device as a secondary processing step after ras processing, achieving higher product quality and improved productivity. [Features] - Introduction of leveling device - Capable of processing high-quality ras products with excellent flatness *For more details, please refer to the PDF document or feel free to contact us.

At Nikken Ras Kogyo, we manufacture precision expanded metal and perforated metal that minimizes misalignment during processing. The quality of our expanded metal and perforated metal minimizes issues such as fraying and misalignment during pressurization, and has been adopted in a wide variety of fields that require precision. We accommodate various non-ferrous metals, including nickel and titanium, and can handle orders starting from just one piece. 【Features of Expanded Metal】 - Lightweight due to being stretched and cut from a sheet! - The mesh stands up during processing, allowing for increased surface area. (Rolling processing is also done in-house.) - There are no seams in the mesh, which distributes the applied load, providing strength. - Good ventilation, lighting, and visibility. 【Features of Perforated Metal】 - Lightweight due to being punched from a sheet! - Compared to expanded metal, it reduces the unevenness of the wire mesh surface. - Combines functionality and strength! *For more details, please contact our official website.

• Manufacturing Technology

The "NAS254N Expandable Metal" is a mesh-like metal sheet made from high corrosion-resistant super stainless steel "NAS254N" that has been processed with a lathing technique to create openings and surface area. It has high chemical resistance and can be used in harsh environments that typical SUS cannot withstand. It has a width of 1100mm, a thickness of 0.8mm, and has a lathing processing record up to SW3mm, and we also accommodate small-scale prototypes on a per-sheet basis. 【Examples of Applications】 ■ Seawater environments: desalination devices, heat exchangers, condenser tubes ■ High concentration chlorine ion environments: pulp and paper industry, various bleaching devices ■ High concentration salt environments: resin manufacturing equipment, reaction vessels and piping for chemicals *For more details, please refer to the materials. Feel free to contact us with any inquiries.

At Nikken Ras Co., Ltd., we believe that our precision metal foil processing technology, developed over more than 90 years since our founding in 1924, can be utilized across a wide range of fields. "Inconel expanded metal" is a heat-resistant and corrosion-resistant alloy primarily composed of nickel, containing elements such as chromium, iron, and carbon, and is used as various processing materials. Generally, Inconel has been considered a difficult alloy to machine due to its high-temperature strength and poor thermal conductivity; however, thanks to the establishment of processing know-how, expanded processing has become possible. We encourage you to make use of our technology in your developed products. 【Features of Inconel Expanded Metal】 ■ Excellent oxidation resistance at high temperatures ■ Strong against stress corrosion cracking caused by Cl- ions ■ Superior corrosion resistance to high-purity water and alkalis ■ Widely used in many chemical industries ■ Expanded processing made possible through the establishment of processing know-how *For more details, please refer to the PDF materials or feel free to contact us.

Our company offers a cleaning process using electrolyzed ionized water to enhance the surface treatment performance of electrode substrates and other materials. We possess "electrolyzed ionized water cleaning," which effectively removes oil stains through high-temperature cleaning. The electrolyzed ionized water generated by our special electrolysis equipment has surfactant effects and high cleaning power. Additionally, the surface tension of electrolyzed ionized water at room temperature (20°C) is equivalent to that of tap water at boiling point (80°C). Furthermore, it is often heated to around 50°C for cleaning, adding thermal energy, which allows us to provide electrode substrates that have undergone a powerful degreasing cleaning process with greater penetration. 【Features】 ■ Effectively removes oil stains with high-temperature cleaning ■ Generates electrolyzed ionized water from regular water for use as a cleaning solution ■ Contains no cleaning chemicals, has high oil-water separation properties, and can be reused *For more details, please refer to the PDF document or feel free to contact us.
