Have you completed the lead-free compatibility for quick-cut brass? 【Tatsumiya Metal's machined parts】
A cutting processing manufacturer "Tatsumiya Metal" that is well-versed in materials! Necessary support for lead-free compliance with European regulations such as RoHS and ELV!
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, in light of the potential removal of this exemption in the near future, it is essential for automobile and electronics manufacturers, as well as parts processing companies supplying components, to respond promptly. 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 make accurate proposals based on our extensive sales record in lead-free brass alloys, particularly "Eco Brass," and our considerable experience and achievements in our own machining division. ● As a material trading company, we have a robust material procurement network. ● Expertise derived from sales experience with materials. + Processing achievements in the machining division! ● Collaborative system with material manufacturers. ● Options available for silicon-based and bismuth-based lead-free copper alloys, as well as low-lead materials. (There are different systems from manufacturers that add silicon and bismuth as substitutes for lead.)

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.
