[Production examples] Machining of environmentally friendly materials such as lead-free brass.
Numerous achievements in mass production using lead-free brass and cadmium-free brass bars on NC automatic lathes! The procurement advantages that can only be provided by Tatsumiya Metal, which has the function of a materials trading company!
Amidst the restrictions on the use of "lead" in various environmental laws and regulations, free-cutting brass that contains about 4% lead for improved machinability is currently exempted due to the lack of effective alternatives. However, prompt action is essential towards the eventual lifting of these exemptions in the coming years. Additionally, since some users establish their own environmental standards, it is also necessary to be prepared to respond at any time. At Tatsumiya Metal, we can provide accurate proposals based on our extensive sales record in the materials sector, including lead-free brass alloys like Eco Brass, as well as our considerable experience and achievements in our machining department. - We are originally a materials trading company, so we have a robust materials procurement network. - We possess know-how derived from our sales record as materials. - Plus, we have machining achievements in our machining department! - We have a cooperative system with material manufacturers. - Options for silicon-based and bismuth-based lead-free copper alloys, as well as low-lead materials, are available (there are systems that add silicon instead of lead and those that add bismuth). We have established a quality system that can meet high technical demands with 45 NC automatic lathe combination machines and high-precision measuring instruments such as roundness measuring devices and surface roughness profile measuring instruments. *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 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.
