アイテック List of Products and Services

"Invar" is a metal material that has the characteristic of very low thermal expansion. It has significant advantages as a metal, including electrical conductivity, solderability, elasticity, and compatibility with welding. Additionally, there is also "Super Invar," which possesses even more excellent properties, with a thermal expansion coefficient less than 1/100 that of iron. 【Features】 ■ A metal material with the characteristic of very low thermal expansion ■ The expansion coefficient of Invar is approximately 1/10 that of iron and nickel ■ It has advantages as a metal, including electrical conductivity, solderability, elasticity, and compatibility with welding *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case of "fine thread assembly processing" conducted at Aitec Co., Ltd. This case was produced using Invar material (FN-36). The processing involved the use of a core jig and careful adjustments of clamping force to prevent deformation of the product during manufacturing. Since the male thread serves as the reference for alignment, we devised the cutting tools and processing paths to ensure that no burrs would form at the tip, allowing the female thread to fit smoothly. 【Case Overview】 ■Material: Invar material (FN-36) ■Processing Details: M31X0.5 alignment processing *For more details, please refer to the related links or feel free to contact us.
