Alloys useful in various fieldsFrom alloys that do not have to be, to alloys that are indispensable.

Company Profile


【Switching from expensive "copper" to inexpensive "iron and copper" for a sustainable society】

From 4G to 5G, from engines to motors, from nuclear power generation to natural power generation. As society progresses at a dizzying pace, the demand for copper continues to rise, and the price is expected to skyrocket. Copper will be gone in only 27 to 8 years, but it is very difficult to imagine a society without copper. In such a society, it has become society's destiny to reduce the use of copper and to use this limited resource with care, and in the midst of calls for SDG's and a sustainable society, we have developed a copper alloy that uses iron, the most abundant and inexpensive resource on earth. This is the birth of a next-generation hybrid alloy that may possibly reduce the consumption of copper in the world in the near future. Due to the difference in melting points and molecular structures, "iron" and "copper" have been considered impossible to alloy because they separate during melting, just like water and oil. In 2016, a prototype was completed, and after further research and development, in 2019, we succeeded in commercializing it to enable mass production. We are currently developing various applications such as mold materials, electrode materials, super antibacterial materials, metal powder materials, and so on.

【Various copper alloys in a form that minimizes copper composition】

With the arrival of EVs, 5G, and the clean energy era, the demand for copper and copper alloys will only increase in the future. How about copper alloys with minimal copper components? Steel is harder than copper, and copper conducts heat and electricity better than steel. We propose the construction of a sustainable society using clean copper alloys with a minimized copper content by adjusting the balance between these two elements. In addition, copper has stronger antibacterial properties against coronaviruses than silver, and antibacterial products using copper have emerged in Europe and the United States. Copper is also known for its extremely high antimicrobial activity against various food poisoning-causing bacteria, drug-resistant bacteria such as MRSA, and viruses including coronaviruses. We have established a technology to give copper's antimicrobial performance to iron. MTA alloys are still in the early stages of development, but we will continue to make a sincere effort to meet your expectations, step by step, for the sake of the "manufacturing industry" in Japan. We look forward to your continued patronage and support.

Representative Director Tetsuro Shibata

We received a comment from Mr. Yasushi Ogura who is the former Vice President and Representative Director of JFE Steel and he graduated from the Department of Metal Engineering, Tokyo Institute of Technology.

During my active career, I have been working with companies and Kawasaki City Hall for the development of the Keihin coastal area. After graduating from the company and participating in Mirai Juku, a group of young management companies in Kawasaki City, I have met many management companies and are supporting them.

Among them, I think the technology of this company is wonderful. From the standpoint of a graduate of the Department of Metal Engineering, according to the equilibrium phase diagram, the maximum solid solution limit of Fe for Cu is about 5% of his, and even if he tries to alloy with the usual dissolution and solidification method, the limit is about 5%.

However, this alloy contains 10% Cu in Fe, which gives the performance of a high-grade beryllium copper alloy. Furthermore, since it can be made into fine powder, it can be expected to utilize 3D printers that use metal powder. As a next-generation metal, we have great expectations for its future success.
