Titanium-added high-tin bronze
チタン添加高鍚ブロンズ

We have 80 percent market share worldwide in manufacturing “titanium-added high-tin bronze” used for bronze method Nb3Sn superconducting wire.

Titanium-added high-tin bronze
 ITER (International Thermonuclear Experimental Reactor), a huge project to study the feasibility of nuclear fusion energy, started in 2007 under combined effort of seven nations and community worldwide. We had exclusively supplied titanium-added high-tin bronze, the material for superconducting wire used in this project. It is an innovative manufacturing method developed by our copper alloy melting technology that has enabled us to supply premium quality material with superconducting property whose conduction rate is twice as high as conventional ones.

Nb3Sn超伝導線用「チタン添加高鍚ブロンズ」で世界シェア80%

2007年、核融合エネルギーの実現性を研究する巨大プロジェクトITER(国際熱核融合実験炉)が世界7か国の協力で始まりましたが、このプロジェクトで使われる超伝導線の素材となるチタン添加高鍚ブロンズを当社が独占供給しました。より高い鍚濃度のブロンズ製造を可能とし、従来の2倍の超伝導特性を持つ高品質の素材を提供できるのは、当社の銅合金溶解技術から生まれた画期的な製造法によるものです。
