Do you have any troubles like this? The metal material you have been using has become difficult to obtain because the existing manufacturer has stopped production...
We apply the manufacturing technology of our product COBARION to offer contract melting of special alloys. We provide integrated production from melting to forging and rolling, and we are also capable of small-scale prototype development. Vacuum melting starts from the formulation of raw materials. Leveraging this strength, we can produce "customer-customized alloys" and support various research and development through metal material prototyping. 【Features】 ■ Capable of manufacturing "customer-customized metal materials" through metal melting ■ Skilled in controlling trace element composition ■ Ingots available in minimum weights of 6kg, 15kg, 30kg, 36kg, and 100kg ■ Can also accommodate subsequent plastic processing (homogenization heat treatment, hot forging, rolling, etc.) ■ We accept contract processing for hot forging and hot rolling as well. ■ We focus on short delivery times. *For more details, please download the PDF or feel free to contact us.

Company information
Aiwa Co., Ltd. Metal Division was established through a collaboration project between the Iwate Prefecture and the Tohoku University Institute of Metal Materials. It serves as the manufacturing base for the cobalt alloy "COBARION," originating from the "Iron Town" of Kamaishi. Utilizing the technical know-how gained from the development and practical application of "COBARION," we engage in the development and manufacturing of various special alloys. From material selection to melting, forging, rolling, and machining, you can rely on Aiwa Metal Division as your one-stop shop for alloy materials. We handle everything from the production of ingots using 30kg and 100kg vacuum melting furnaces to hot plastic processing with a 600-ton hydraulic press and rolling mill, accommodating small-scale prototypes and development that are difficult for major special alloy manufacturers to manage. We also have a track record of joint development of functional metal materials such as special steels, magnetic materials, resistive materials, and spring materials that are hard to obtain in the market, as well as original alloys customized for our customers. We are confident that we can be of assistance as a material developer and supplier.
