Brass, copper alloys, brass materials, prototype and mass production support for EV and bus bars!
Mitsui Sumitomo Metal Mining Copper Alloy, Mitsubishi Copper Alloy, PMC materials, and other companies have achievements.
For prototyping busbars, terminals, and terminal materials! Coils, plates, and plated materials can be procured as needed from our in-house inventory and procurement network.
Tatsumiya Metal's metal material sales can provide high-quality, short-term supply of non-ferrous metal materials and plated materials thanks to our extensive in-house inventory and slitting equipment. Typically, the delivery time for standard material supply is about 1 to 10 days for coil materials, but at Tatsumiya Metal, we maintain inventory and perform in-house processing, allowing for same-day shipping and next-day delivery at the earliest. (Note: standard 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, and we respond to shipping needs based on application and urgency. We also quickly respond to requests for prototype materials in sheet form. This reduces inventory risk, allowing for the supply of only the necessary amount of materials when needed. 【Features】 - Stock of various copper alloy materials and plated materials available - Supported by in-house and external slitting equipment - Through our supply network, we can also provide and propose prototype materials in coil and standard sheet forms beyond our in-house inventory. - A supply system established through a network with domestic and international copper alloy manufacturers Additionally, we can accommodate both prototyping and mass production of thick copper materials for busbars, which have seen increasing demand in recent years. *For more details, please download our catalog or contact us.*

Company information
<Metal Materials Trading Division> With a rich inventory and four slitting facilities, we supply materials nationwide from our Higashi-Osaka Coil Center. We specialize in the sale of copper alloy materials and non-ferrous metal materials. In addition to traditional copper alloy materials, we are actively promoting the next-generation copper-aluminum clad material "CCA" in collaboration with ACM (Applied Composite Material Corp.). <Metal Processing Division> We excel in processing small quantities of a wide variety of metal pipes. Our diverse techniques 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 residential applications. In the world of bending processing, where small lots are common, the presence or absence of molds becomes quite important. We propose a mix of our own molds and equipment, as well as those from partner factories. Additionally, our precision cutting processing using NC automatic lathes leverages the procurement advantages unique to Tatsumiya, which has a metal materials trading division, enhancing customer satisfaction through technical expertise, procurement power, 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.
