basic information
【Manufacturing Method of Niobium Tubes】 - Niobium tubes are produced through hot extrusion. After electromagnetic induction heating (600°C), secondary electromagnetic induction heating (1150°C) is performed, followed by reaming. The reduction in surface area is less than 20%. Next, tertiary electromagnetic induction heating (1200°C) is conducted, and then shaping and extrusion processing take place. The extrusion ratio is below 10%, and the reduction in surface area is less than 90%. After air cooling, final shaping is done, completing the hot extrusion process. - Niobium seamless tubes manufactured using this method ensure sufficient thermal process plasticity. The risk of niobium fluidity is eliminated with this manufacturing method. It meets the performance and dimensional tolerance requirements of the users.

Company information
Our company supports the foundational industries that sustain the Japanese economy. - In manufacturing, obtaining materials has become critical. There are special materials that are difficult to procure in small lots. We negotiate directly with major overseas companies to provide any special materials quickly. [Titanium, Zirconium, Tantalum, Niobium, Tungsten, Molybdenum, and their alloys] - These are functional components that ensure the performance and reliability of products. We provide highly reliable functional components developed through research and collaboration with overseas companies at short lead times and low costs. [Split roller bearings, reducers, and increasers] - We offer stirring technology, which is a key technology in various plants. We propose optimal stirring conditions according to the customer's process. [Stirrers, stirring simulations, magnetic drives, bottom stirring] - We provide ultra-large forged products with short lead times. We guarantee forging quality through free forging using some of the world's largest forging equipment. [Roll mills, forged flanges, wind power generation components] - Special attachments that excel in civil engineering demolition and disaster recovery work. They replicate human movements through rotation from the arm.
