Our "Mercury Target Vessel No. 10" installed at J-PARC is now operating smoothly.
The mercury target vessel No. 10 manufactured by Metal Technology Co. Ltd. was installed at the Japan Proton Accelerator Research Complex (J-PARC), which is operated by the Japan Atomic Energy Agency (JAEA), in November 2020. J-PARC started at 600kW beam operation after the installation of the mercury target vessel, and has been operating smoothly for 106 days at 600kW and 10 days at 700kW (as of 14 April), supplying neutrons to many neutron experimental lines and supporting cutting-edge research. In July 2021 we plan to run the unit up to the world's highest operation of 1MW.
ITER orders brazed Tungsten and copper parts for fusion reactor
A recent article was published by Nikkan Sangyo Shimbun on March 25th highlighting parts ordered by ITER from Yamato Gokin Co. Ltd. In the article it describes that essential parts for the divertor for the fusion reactors were made using the highly skilled bonding technology of Metal Technology Co. Ltd. (MTC). MTC has developed and advanced a brazing technology for the dissimilar metals of tungsten and copper alloys. These materials have very different thermal expansion coefficients and are used in environments with surface temperatures of over 1000°C.
As an expert in bonding dissimilar metals, MTC was able to meet this challenge and provide what the customer needed. MTC continues to challenge and make advancements in the area of bonding and brazing for materials that can withstand the harshest of environments.

Notice of withdrawal from MRO
Metal Technology Co. Ltd. have come to the decision to withdraw from the MRO business and with this action MTC will also close Chiba Plant.
This is effective from March 1st, 2021.

For any inquiries regarding this matter please contact Ms. Miho Norinaga at
