USUI CO., LTD. List of Products and Services

Reliable zinc-based and nickel-based coatings are widely applied for rust prevention treatments of automotive components. However, the inner and outer surfaces of tubes manufactured by Usui International Industry Co., Ltd. are treated with uniquely developed zinc-based and nickel-based rust prevention treatments tailored for various applications. The inner surface treatment of the tubes is applicable only to single-layer rolled steel pipes. 【Features of Inner Surface Treatment of Tubes】 ○ Nickel → Prevents copper leaching, suitable for alcohol fuel and sour gasoline countermeasures. ○ HINIC (Multi-layer Ni) → Improved corrosion resistance, suitable for alcohol fuel and sour gasoline countermeasures.

Our "Amorphous Technology" features amorphous metals with high corrosion resistance, wear resistance, and excellent magnetic properties, which are applied as coatings on thin plates or substrates through our unique rapid cooling spray method. Due to its high sensitivity to deformation, it enables non-contact strain detection. 【Features】 - Capable of forming a highly corrosion-resistant coating on the surface. - Exhibits excellent wear resistance due to its high hardness and lack of crystalline structure. - Possesses excellent magnetic properties without directional dependence. - Enables non-contact strain detection due to high sensitivity to changes in magnetic properties when deformed. - Capable of producing thin plates over 300μm (conventional methods produce 50μm foils). - We are currently providing materials that introduce examples of applications using amorphous technology. *For more details, please refer to the PDF document or feel free to contact us.

At Usui International Industry Co., Ltd., we offer "amorphous thermal spraying" for components. By changing the material, the thermal spray coating can achieve high corrosion resistance and wear resistance. When applied to slurry pump impellers and similar components, it is possible to reduce wear and the frequency of replacements. If you are facing durability challenges with components used in harsh environments that require both corrosion and wear resistance, please feel free to consult us. 【Features】 ■ High corrosion resistance and wear resistance can be achieved by changing the material. ■ When applied to slurry pump impellers and similar components, it is possible to reduce wear and the frequency of replacements. *For more details, please download the PDF or feel free to contact us.
