Revolutionizing Stainless Steel with L・Core® for Eco-Friendly Solutions

Japan Metals Co., headquartered in Minato, Tokyo, is making strides in the world of functional stainless steel with its innovative product, L・Core®. This product leverages a unique surface modification technology to ensure that the natural corrosion resistance of stainless steel is maintained while achieving significantly low contact resistance. As an eco-friendly product, L・Core® is being positioned to reinforce the company's commitment to sustainable practices.

Background: Creating Conductive Stainless Steel

Historically, stainless steel has been known for its formidable corrosion resistance, primarily due to a passive oxide layer. However, this layer also gives rise to an inherent resistance to electrical conductivity, necessitating the use of costly nickel plating or conductive tape for components requiring electrical properties. L・Core® solves this issue by integrating conductive pathways within the material itself. This breakthrough allows for streamlined processes, substantial cost reductions, and a lower environmental footprint.

Technical Features: Forming Conductive Pathways within the Passive Layer

Japan Metals has developed a proprietary surface treatment technology that enables the formation of 'carrier dopes' within the passive layer of stainless steel. This refinement ensures both conductivity and corrosion resistance remain uncompromised, providing:

- Conductivity without Compromise: The passive layer is modified without destruction, retaining the core corrosion-resistant properties of stainless steel.
- No Post-Processing Required: The low-resistance nature of L・Core® allows it to be used as a conductive component without the need for additional processes such as plating.

Performance Data: Superior Contact Resistance and Stability

L・Core® showcases contact resistance values comparable to semi-gloss nickel plated materials and exhibits impressive performance consistency even in harsh environmental conditions. Key metrics include:

- Low Contact Resistance: L・Core® demonstrates significantly lower resistance than standard SUS304 materials.
- High Reliability: After 2,700 hours at 60°C and 95% relative humidity, L・Core® shows minimal performance degradation, highlighting its durability.

Benefits of Adoption: Cost Efficiency and Enhanced Quality

Compared to nickel-plated stainless steel, L・Core® presents advantages in both cost and quality, positioning it as a favorable option in various applications.

Product Specifications and Manufacturing Range

L・Core® can be produced using various austenitic stainless steels (such as SUS301, SUS304) with the following:

- Thickness: Ranging from 0.05mm to 0.30mm
- Width: Up to 200mm
- Finish: Compatible with all finishes except for TA (tension annealed).
