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... ○ The material with the specified alloy number in the drawing cannot be procured. It is indeed listed in the JIS standards, but... Chemical compositions and mechanical properties are easily obtainable. Typically, designers specify the best material among them in the drawings. However, the actual availability of that material when doing the work 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.
![[Production examples] Machining of environmentally friendly materials such as lead-free brass.](https://image.mono.ipros.com/public/product/image/5bf/2000435380/IPROS11415096575018895330.JPG?w=280&h=280)
Numerous achievements in mass production using lead-free brass and cadmium-free brass bars on NC automatic lathes! The procurement advantages made possible by Tatsumiya Metal, which has the functions of a materials trading company!
Amidst the restrictions on the use of "lead" in various environmental laws and regulations, free-cutting brass containing about 4% lead for the purpose of improving machinability is currently exempted due to the lack of effective alternative materials. However, prompt action is essential towards the eventual lifting of this exemption 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 make precise proposals based on our extensive sales record in the materials division, including lead-free brass alloys such as Eco Brass, and our considerable experience and achievements in our machining division. - As a materials trading company, we have a robust material procurement network. - We possess know-how gained from our sales experience with materials. - Plus, we have processing achievements in our machining division! - We have a cooperative system with material manufacturers. - We offer various lead-free copper alloys, including silicon-based and bismuth-based options, as well as low-lead materials (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.
Of course, we provide high-quality materials, and you can order from just one piece or one item!
- Our company accepts orders starting from just one material. While some suppliers require a minimum order quantity, we are happy to accommodate small lots. Customers appreciate being able to order exactly what they need when they need it. - For urgent orders such as "I need the product delivered immediately" or "I suddenly need materials," you can rely on us. Depending on the products and stock availability, same-day shipping is possible. We respond quickly to ensure our customers are not kept waiting. - We use a "high-precision cutting machine (micro-cut)" for cutting materials. Unlike standard cutting machines that leave saw marks on the cut surface, our high-precision cutting machine achieves a smooth finish. This means there is no need for customers to process the cut surface to remove saw marks before use, eliminating unnecessary work and reducing processing time.
