In response to the growing demand for higher performance and faster processing in analytical and medical devices, NIPPON KINZOKU has developed two innovative products based on its FINE PIPE technology: "High-Precision Inner Surface" small-diameter tubes and "FINE PEEK-ST" stainless steel and PEEK resin composite tubes. These products align perfectly with the industry's shift toward extreme precision, resulting in a surge of inquiries and expanding orders for the “FINE PIPE” series.

NIPPON KINZOKU’s “FINE PIPE” Series Welded Drawn Pipes Outperforming Seamless Pipes

Conventional TA (Tension Annealing) finish has been highly evaluated as a stainless spring material with excellent flatness, low residual stress, and dimensional stability after processing. STA finish, which is a further evolution of this finish, minimizes residual stress and is optimized for etching processing.

NIPPON KINZOKU: New Launch of “STA Finish” Stainless Steel for High-Precision Etching as an “Eco-Product”

Eliminate machining chips leads eco-friendly process, and conventional fixed-length products require set-up for each piece, resulting in losses, but continuous processing of coiled products can reduce these losses. (Graphic: Business Wire)

Stability of the welded part of the bare tube and cutting surface of the material, which will not rupture even when thinly drawn: The ratio between the fractured and sheared surfaces is agreed to facilitate welding by medical device manufacturers. The same end-face properties are supplied for the entire coil length (0.2 mm: approx. 4,000 M). (Graphic: Business Wire)

Fine Profile is a generic term for products made by continuously processing ferrous and nonferrous metals into irregularly shaped cross sections with different thicknesses in the width direction using our unique rolling technology. It contributes to customers' process reduction, environmental improvement, manufacturing cost reduction, and yield improvement as an alternative to various processes such as cutting and grinding.

NIPPON KINZOKU’s Cold Profile Rolled Products Are Named "Fine Profile” to Strengthen Sales Expansion

We have developed our own “FI finish”, a stainless steel surface pre-coated with an inorganic coating (about 1μm in thickness) that offers electrical insulation resistance.

NIPPON KINZOKU Co-Creating New Value with Rolling Technology Develops Insulated Stainless Steel FI (Fine Insulation) Finish

While conventional stainless steel excels in corrosion resistance due to its "passive film," this same film typically acts as an electrical insulator. Consequently, components requiring conductivity have traditionally relied on high-cost nickel (Ni) plating or conductive tapes. L-Core solves this challenge by making the passive film itself conductive. This breakthrough ensures high conductivity in the material alone, streamlining the manufacturing process and achieving significant cost reductions alongside a lower environmental footprint.

NIPPON KINZOKU Strengthens Promotion of "L-Core" as an Eco-Product: Functional Stainless Steel Achieving High Conductivity via Surface Modification

FB (Fine Black®): An extremely thin transparent oxide film is formed on the surface of stainless steel to achieve a metallic look and deep black color through light interference and absorption phenomena. The surface is treated with a special hard film to provide excellent corrosion and wear resistance. M-FB (Matte FB): Developed “Matte tone” FB finish to meet the market need for “matte” products. BA5 (Bright Annealing): In addition to the general metallic glossy BA finish (surface finish by bright heat treatment after cold rolling), the “BA5” finish is even higher glossy by our proprietary technology. PW (Pearly White): Finished in stainless steel with a calm satin tone (aluminum tone). (Graphic: Business Wire)
