We introduce a wide range of standard Invar alloys and free-cutting super Invar alloys.
We would like to introduce the 'Invar' products handled by Shinboko Steel Co., Ltd. Starting with "IC-36," which has a thermal expansion coefficient of 1.5 ppm or less, which is less than 1/10 of that of stainless steel, we also offer the super Invar alloy "IC-36S," which has a low thermal expansion coefficient, and the free-cutting super Invar alloy "IC-36FS," among others. Additionally, we have various Invar alloys "IC-363/IC-364/IC-365" available, which can be adjusted for thermal expansion coefficients according to customer requests. 【Product Lineup】 ■IC-36 ■IC-36S ■IC-36FS ■IC-363 ■IC-364 ■IC-365 *For more details, please refer to the PDF materials or feel free to contact us.

Company information
Our company started in 1949 as a special steel manufacturing company in Kawagoe City, Saitama Prefecture. During this time, we have supported the foundation of Japanese manufacturing as a proposal-based special steel manufacturer, developing metal materials tailored to our customers' needs. Our main product, low thermal expansion alloys, can adjust the coefficient of thermal expansion from zero to 1 ppm. By developing alloys that meet our customers' diverse needs, such as corrosion resistance, machinability, and rigidity, we possess a wide range of low thermal expansion alloy materials and can recommend and provide materials that are suitable for your use.
