Brass, copper alloys, brass materials, automotive parts, EV, prototype and mass production support for busbars!
Mitsui Sumitomo Metal Mining Copper Alloy, Mitsubishi Copper Alloy, PMC materials, and next-generation copper-aluminum clad material "CCA".
Also for prototyping busbars, terminals, and terminal materials! Coils, plates, and plating materials can be procured in necessary quantities when needed through our in-house inventory and procurement network.
Tatsumiya Metal's metal material sales can provide high-quality non-ferrous metal materials and plated materials with short delivery times, thanks to our extensive in-house inventory and slitting equipment. Typically, the delivery time for standard material supply, such as coil materials, takes about one week to ten days. However, at Tatsumiya Metal, we maintain inventory and perform in-house processing, allowing us to ship on the same day as the order and deliver the next day at the earliest. (Note: The usual delivery time is 4 to 5 days.) The minimum lot size for coil materials is usually 2 kg/mm. For prototypes, we can provide materials in units of a few centimeters, allowing us to respond to shipping needs based on application and urgency. We also quickly accommodate requests for prototype materials in sheet form. This approach reduces inventory risk, enabling material supply only as needed when required. **Features** - Stock of various copper products and plated materials - Support from in-house and external slitting facilities - Through our supply network, we can provide and propose prototype materials in coil form and standard-sized sheets beyond our in-house inventory. - We have established a supply system through a network with domestic and international copper product manufacturers. Additionally, we can accommodate both prototypes and mass production of thick copper materials for busbars, which have seen increasing demand in recent years. *For more details, please download the catalog or contact us.*

Company information
<Metal Materials Trading Division> With a rich inventory and four slitting facilities, we supply from the Higashi-Osaka Coil Center to the entire country. We specialize in the sales of copper alloy materials and non-ferrous metal materials. We are also actively proposing the next-generation copper-aluminum clad material "CCAC" in collaboration with Applied Composite Material Corp. <Metal Processing Division> We excel in processing small quantities of various metal pipes. Our diverse technologies include coil winding, R-bending, various bending processes, and welding. We handle everything from one-off parts used in heat exchanger components and machinery to larger quantities for automotive, consumer, and housing equipment. In the world of bending processing, where small lots are common, the presence or absence of molds becomes quite important. We mix our own molds and equipment with those from partner factories to provide tailored proposals. Additionally, our NC automatic lathe precision cutting processing leverages the procurement advantages unique to Tatsumiya, which has a metal materials trading division, enhancing customer satisfaction through technical expertise, procurement capabilities, and cost efficiency. With over 90 years of establishment as a processing trading company, we view the 100-year mark as a milestone and will continue to build a great company in the future.
