High hardness and excellent functionality for fine components! In addition to high wear resistance and electrical conductivity, it also excels in low contact resistance.
"Hard Gold Plating" offers high wear resistance and electrical conductivity, as well as excellent solderability and low contact resistance. By containing cobalt, its hardness is improved several times compared to pure gold plating. Due to its excellent wear resistance and high electrical conductivity, it is mainly used in parts with frequent movement, such as contact points in electronic device switches. It is also suitable for gold plating of various connectors, contacts, and fine components. Our company, through its unique know-how, is capable of achieving uniform plating on the inner surfaces of fine components such as pins and fine-diameter pipes like contact probes. 【Features】 ■ High hardness and excellent functionality ■ High wear resistance ■ High electrical conductivity ■ Low contact resistance ■ Hardness improved several times compared to pure gold plating ■ High electrical conductivity *For more details, please refer to the PDF document or feel free to contact us.

Company information
Surface treatment technologies, including plating, have continuously advanced and developed as familiar technologies in our daily lives. It is said that gold plating was applied to ancient decorative items, including the Great Buddha of Todai-ji in Nara. The pure desire to adorn objects more beautifully and to maintain that beauty forever has remained unchanged from ancient times to the present. Moreover, modern surface treatment technologies are not limited to purposes such as decoration and rust prevention; they are applied in various industrial uses. For example, many needs, such as wanting to harden the surface of a product, enhance conductivity, or reduce friction coefficients, can be achieved relatively cost-effectively through surface treatment technologies primarily based on plating. Since its establishment, Eputec Co., Ltd. has responded to various surface treatment needs of the times, consistently pursuing technological and production innovation. The key phrase is "Innovation for Tomorrow." Eputec Co., Ltd. will continue to respond to increasingly sophisticated and diversified needs and contribute to society as a "value-creating company" through surface treatment technologies that pave the way for tomorrow.
