Nippon Steel & Sumitomo Metal Corporation and Toho Titanium Co Ltd with the objective of responding to the growing
demand for titanium alloy products for aerospace, have agreed to establish and operate a joint venture to produce titanium
ingots (intermediate products), on a commission basis, and have entered into a joint venture agreement.
For the production of titanium-alloy ingots for aerospace applications, a most appropriate setup is considered to be a
combination of two kinds of furnaces, one being the EB (electron beam) furnace, which is very advantageous in raw
materials selection, permitting the use of a great variety of scrap, and the other being the VAR (vacuum arc remelting )
furnace capable of assuring homogeneity of chemical compositions.
