Nihon Superior Group

What Nihon Superior Group does

Nihon Superior Co., Ltd. (株式会社日本スペリア社) is a privately held Japanese manufacturer of metal bonding materials headquartered in Suita City, Osaka. Founded over 50 years ago, the company has evolved from a brazing materials supplier into a specialist in lead-free solder alloys, nano-silver sintering pastes, fluxes, and brazing materials. It serves automotive electronics manufacturers, general electronics assemblers, semiconductor packagers, and industrial metal-joining customers, with named validation in the automotive supply chain (e.g., TDK Malaysia recognition). Its primary customer segments are automotive electronics (crack-resistant, heat-cycling-durable solder) and general electronics (semiconductors, power modules, LED displays, mobile devices), with industrial brazing as a secondary segment.

The company's core technology rests on proprietary lead-free alloy formulations. Its flagship SN100C family (Sn-Cu-Ni-Ge silver-free alloys) holds ISO international certification and more than 20 years of commercial track record; variants include SN100CV (Bi-enhanced for strength), LF-C2 (high-strength crack-resistant), LF-Z3 (anti-silver-leaching for automotive heated wire glass), TipSave N (tip-wear prevention), and TempSave (Sn-Bi low-temperature below 200°C). A second technology pillar is the Alconano nano-silver sintering paste platform (ANP series) and the ASTRO series (HP/LP/LN) for semiconductor die bonding and power-device packaging, using nanometer-size silver particles coated with alcohol derivatives. Products are offered across all form factors — bars, wires, pastes, balls, preforms — with companion fluxes and brazing materials.

Nihon Superior generates revenue through direct hardware sales of metal bonding products in Japan and through a global network of licensed manufacturers and distributors for SN100C technology — FCT Assembly (USA), AIM (Canada/HK), DKL Metals (UK), Stannol (Germany), plus partners in Spain, Brazil, China, and Hong Kong. A wholly owned Thailand subsidiary (NSM) serves Southeast Asia with its own delivery fleet. Pricing is not publicly disclosed; customers engage via website contact forms or phone. The company is led by President Tetsuro Nishimura and is privately held with no identified institutional investors, parent company, or public listing.
