Nippon Kinzoku Unveils Eco-Friendly Stainless Steel For High-Precision Etching

KUALA LUMPUR, Aug 21 (Bernama) -- Nippon Kinzoku Co Ltd has launched its fourth environmentally friendly “Eco-Product” series, the Special Tension Annealing (STA) finish stainless steel, aimed at reducing warping and refining crystal grain size for high-definition etching.

According to the company in a statement, STA finish significantly improves dimensional stability by minimising warping in the etching process, particularly in half-etching applications.

It also produces finer crystal grain sizes, making it suitable for high-precision microfabrication such as smartphone components, metal masks and wrapping carriers.

The product enables process simplification, enhances energy efficiency, reduces environmental impact and provides greater design flexibility for improved manufacturing yield.

Certified as an official “Eco-Product”, the STA finish aligns with the company’s goal of achieving net zero carbon dioxide emissions by 2050 and supports sustainable manufacturing through eco-friendly materials.

The development is also part of its 11th management plan, “Nippon Kinzoku 2030”, focused on “Near Net Performance” — delivering final-product-level performance directly from the material stage, with plans to expand applications in 5G communications, mobile devices and semiconductor-related products.
