It seems like it should exist but it really doesn't! "List of Availability of Metal Materials by Type and Shape" Is this alloy really in the JIS? At times like this!

Have you ever had such an experience? ○ You created a new drawing, but you're worried if this material really exists in the world... ○ It's a drawing for a shape processed from a rod, yet the alloy number for a plate is specified... ○ You can't procure the material with the alloy number specified in the drawing. It is indeed listed in the JIS standards, but... Chemical composition and mechanical properties data are easily accessible. Typically, designers specify the best material in the drawing, often overlooking the availability of that material itself. This is understandable since there are no such references or textbooks available. Therefore, I hope you can use this "Availability Reference Table" as a resource for your work.

It seems like it should exist but doesn't quite! "List of Availability of Metal Materials by Type and Shape" Is this alloy really in the JIS? At times like this!

Have you ever had such experiences? - You created a new drawing, but you're worried if this material actually exists in the world... - It's a drawing for a shape processed from a rod, yet a plate alloy number is specified... - You can't procure the material with the specified alloy number in the drawing. It is indeed listed in the JIS standards, but... Chemical compositions and mechanical properties are easily accessible. Typically, designers specify the best material in the drawing from among these. However, the actual availability of that material when doing the job tends to be overlooked. This is understandable since there are no such references or literature available. Therefore, I hope you can use this "Availability List" as a reference to assist you in your work.

Have you completed the lead-free compatibility for quick-cut brass? 【Tatsumiya Metal's machined parts】

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.)

Brass, copper alloys, brass materials, prototype and mass production support for EV and bus bars!

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.*
