[Machining Examples of Difficult-to-Cut Materials] Invar

It is used to manufacture precision instruments that want to avoid the effects of heat due to its low thermal expansion coefficient.

"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.
