松原工業 List of Products and Services

We handle springs for spring pin connectors. We offer "conductive spring wire," which achieves excellent tensile strength and conductivity by coating copper wire with SUS tubing, as well as "TCC wire," which excels in workability and solderability, contributes to cost reduction, and allows for high strength and reduced diameter, thus providing excellent bend resistance. We will continue to strive to meet the increasingly diverse needs of our users. Please feel free to contact us with any requests. [Features] ■ Superior strength and durability compared to general copper alloys ■ Material design can be tailored to a wide range of required characteristics *For more details, please download the PDF or feel free to contact us.

We handle stainless steel wire for hydrogen environment springs, "Facile." It maintains high strength (equivalent to SUS304WPB), high toughness, and high fatigue strength (equal to or greater than SUS304WPB and SUS631J1) under low-temperature, high-pressure hydrogen atmospheres. Through stainless steel wire with excellent hydrogen embrittlement resistance, we contribute to the upcoming hydrogen society. Please feel free to contact us if you have any inquiries. 【Wire Diameter (mm)】 ■0.50 ■1.00 ■1.50 ■2.00 ■2.50 *For more details, please download the PDF or feel free to contact us.
