This product is an electrode designed to prevent reverse attachment of welding nuts. Traditionally, it was common to create electrodes by joining electrode materials with insulators and carbon steel, but this product allows for miniaturization of the electrode itself by using a metal with an insulating coating. Additionally, by adopting a structure that allows for the replacement of only the worn welding point, significant reductions in running costs can be expected. 【Features】 ■ Wide range of processing from 2mm to lengths of 3m, and up to 400mm in diameter for round materials ■ From small lots of 1 piece to mass production ■ Machining, deep hole processing, bending processing, and joining processing ■ Compatible with various workpieces using the five-axis composite machining center "DMU 65 monoBLOCK" ■ Cutting possible with water jet regardless of material *For more details, please download the PDF or feel free to contact us.

"Brass" is an alloy of copper and zinc, and is a type of copper alloy. The addition of zinc significantly reduces conductivity, but it has excellent workability and is widely used in many fields beyond resistance welding, making it a popular metal. At Natsume, we use this material for parts such as adapters and horns. Please feel free to contact us when you need assistance. 【Features】 ■ Wide range of processing from 2mm to lengths of 3m, and round material processing up to a maximum of 400φ ■ From small lots of 1 piece to mass production ■ Cutting, deep hole processing, bending, and joining ■ Compatible with various workpieces using the five-axis machining center "DMU 65 monoBLOCK" ■ Cutting possible with water jet regardless of material *For more details, please download the PDF or feel free to contact us.

"BeCu" is a copper alloy that incorporates beryllium, significantly increasing its hardness. It is distinguished as BeCu50 and BeCu25 according to the beryllium content, with the numbers 50 and 25 representing guidelines for their respective conductivity. The higher the beryllium content, the lower the conductivity, but the hardness increases. Our company can process such "beryllium copper." 【Features】 ■ Wide range of processing from 2mm to lengths of 3m, and round material processing up to a maximum of 400φ ■ From small lots of 1 piece to mass production ■ Cutting, deep hole processing, bending, and joining ■ Compatible with various workpieces using the five-axis machining center "DMU 65 monoBLOCK" ■ Cutting possible with water jet regardless of material *For more details, please download the PDF or feel free to contact us.

"Alumina-dispersed copper" is a special copper alloy made by mixing copper and alumina powders. It has a higher hardness than chromium copper and good conductivity. Furthermore, it has less reduction in hardness at high temperatures, making it suitable as a material for electrode components used in welding demanding materials such as special plated steel sheets. Our company can process such "alumina-dispersed copper." 【Features】 ■ Wide range of processing from 2mm to lengths of 3m and round materials up to a maximum of 400φ ■ From small lots of 1 piece to mass production ■ Cutting, deep hole processing, bending, and joining ■ Compatible with various workpieces using the five-axis machining center "DMU 65 monoBLOCK" ■ Capable of cutting materials of any kind with a water jet *For more details, please download the PDF or feel free to contact us.

"Chrome copper" is an alloy that combines approximately 1% chromium with copper. Compared to tough pitch copper, the addition of chromium slightly reduces conductivity, but it increases hardness and resistance to pressure, making it widely used in tip electrode components such as cap chips. At Natsume, we initially propose it as a general electrode material, and it is not an exaggeration to say that it is a metal specifically for electrodes. [Features] ■ Wide range of processing from 2mm to lengths of 3m and round material processing up to a maximum of 400φ ■ From small lots of 1 piece to mass production ■ Cutting, deep hole processing, bending, and joining ■ Compatible with various workpieces using the five-axis machining center "DMU 65 monoBLOCK" ■ Cutting possible with water jet regardless of material *For more details, please download the PDF or feel free to contact us.

"Tough Pitch Copper" is what is commonly referred to as pure copper, with a composition of 99 percent copper. Due to its high conductivity, it is suitable as a material for power supply components. However, because of its low height, it is not suitable for electrodes in equipment subjected to strong pressure. Additionally, it is prone to distortion, making its workability worse compared to other materials. Our company can process such "Tough Pitch Copper." 【Features】 ■ Wide range of processing from 2mm to 3m in length and up to 400φ for round materials ■ From small lots of 1 piece to mass production ■ Cutting, deep hole processing, bending, and joining ■ Compatible with various workpieces using the five-axis machining center "DMU 65 monoBLOCK" ■ Capable of cutting regardless of material with a water jet *For more details, please download the PDF or feel free to contact us.

Non-ferrous metal processing is a niche industry, so there are very few tools available for non-ferrous metal processing, and the variety is limited. Therefore, our company uniquely processes general-purpose tools to standardize them for our use, thereby increasing manufacturing efficiency. For products made of copper and copper alloys, there are many consumables like electrodes, so surface polishing may be neglected, minor scratches may be overlooked, and some manufacturers may not pay attention to deburring even if there are slight burrs after cutting, drilling, or molding. However, our products do not have such shortcuts. In recent years, we have also started receiving orders in the fields of resin processing, rare metal processing, ceramic processing, and carbon processing. Utilizing the advanced processing technology cultivated in the manufacturing of copper products, our specialized technology enables the processing of parts in various fields, fundamentally solving our customers' "troubles." *For more details, please refer to the PDF document or feel free to contact us.
