Abstract

OSAKA Titanium technologies Co., Ltd. recently increased its annual production capacity for titanium sponge by 6,000 tons, from 18,000 to 24,000 tons per annum. Behind this expansion is robust demand from the aircraft industry, where about half of our titanium sponge product is utilized, combined with steady requirements on the part of the electric power and chemical industries, the other major users of our product.This report provides a general overview of our titanium manufacturing system by the Kroll method and the corresponding expansion of production capacity that was recently implemented. It also describes quality improvement measures that have been taken in regard to high-purity titanium for semiconductor use.At present, titanium sponge is in short supply and each and every supplier worldwide is attempting to cope with the situation by increasing capacity. As a swift response to this global trend, OSAKA Titanium technologies Co., Ltd. has proactively worked to resolve this capacity issue and, at the same time, is prepared to further improve our product quality and cost competitiveness, the most likely arenas of competition once the imbalance in supply and demand is eliminated.
