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! When it is necessary to comply with European regulations such as RoHS and ELV for lead-free requirements!
Amidst the restrictions on the use of "lead" in various environmental laws and regulations, free-cutting brass that contains about 4% lead for the purpose of improving machinability is currently exempted due to the lack of effective alternative materials. 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 the parts processing companies supplying them, 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 Tsumiya Metal, we can make accurate proposals based on our extensive sales record of lead-free brass alloys, particularly "Eco Brass," and our significant experience and achievements in our own machining division. ● As a material trading company, we have a robust material procurement network. ● Know-how gained from sales experience as a material supplier. + Machining achievements in our processing division! ● Collaborative system with material manufacturers. ● Options available for silicon-based and bismuth-based lead-free copper alloys, as well as low-lead materials (each manufacturer offers variants with silicon or bismuth added as substitutes for lead).

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.
