FB (Fine Black): Delivers a deep, metallic black through light interference and absorption via an ultra-thin, transparent oxide film. The surface undergoes a specialized hardening treatment to ensure exceptional corrosion and wear resistance. M-FB (Matte Fine Black): A matte version of the FB finish developed to meet market demand for low-glare textures, adding a subdued, premium elegance to the FB series. BA5 (Bright Annealing): Our standard BA finish, utilizing proprietary technology, it achieves a superior luster compared to conventional bright annealing. PW (Pearly White): A satin-matte finish designed for a refined, "white" aesthetic and a calm, sophisticated texture. Available in a range (PW3–PW10) to suit different roughness requirements.

Product Features and Benefits
NIPPON KINZOKU’s "Decorative Stainless Steel Finishes for Exterior Use" offer a diverse range of aesthetic options and are widely used in automotive exterior trims and housings for smartphones and mobile PCs.
Our core strength is "coil-to-coil" continuous processing, a technology refined through decades of cold-rolling expertise. This enables us to deliver unique designs and consistent quality with high productivity.
Since the decorative finish is integrated directly into the material, the products offer the following strategic advantages:

• Process Simplification: Eliminates the need for secondary polishing, painting, and surface treatments (e.g., anodizing), resulting in higher production yields and lower total costs.
• Reduced Environmental Impact: Minimizes CO₂ emissions by streamlining manufacturing stages. As an "Eco-Product," this lineup supports the global transition to carbon neutrality by 2050.

Design Variations (Surface Finish Lineup)
The following finishes are available to meet specific application requirements and design concepts:
