ABOUT COMPANY
Industrial materials supported by
a one-of-a-kind technology in Japan
In 1970, the Company established the manufacturing process for phosphorous master alloy using yellow phosphorous, a challenging substance to handle with a combustion flashpoint of 30°C.
Since then, Osaka Alloying Works is the only business in Japan that carries out the extremely difficult process of handling and alloying yellow phosphorous with other metals.
The company also manufactures cast copper alloys, titanium-additive bronze for niobium-tin (Nb3Sn) superconducting wires used in nuclear magnetic resonance (NMR) equipment, and sheet metal for cymbals.
The Company also went on to acquire a patent in 1984 for the Mizuta melt-solidification process of manufacturing copper alloys in uniform concentrations via rapid cooling with water showers.
Going forward, Osaka Alloying Works will continue to dedicate ourselves to expanding the potential of alloying technologies.
Constantly improving technologies
and reliably delivering high-quality products
Osaka Alloying Works Co., Ltd. became a subsidiary of JX Advanced Metals in June 2023. Going forward, we will leverage the manufacturing techniques for all varieties of master alloys which we have cultivated over our history stretching back to 1935, passing these on and utilizing our unique melting processes to satisfy our customers' requirements.
As a Fukui-based company, we stand alongside society, providing high-quality products and technical advancements reliably as we strike to contribute toward social progress.

Osaka Alloying Works Sustainability Programs
- Process water recycling
- We utilize a self-recycling format for our equipment cooling water.
We recycle our cleaning and processing water for exhaust gas processing.
This results in around 90% of the water used in our plants being recycled and used again.
- Made with recycled materials
- We use recycled materials for the metals (particularly copper) in our products.
