Product Description

Overview
Iron fixed expansion alloys are a series of fixed expansion alloys that can be matched with soft glass and ceramics with different expansion coefficients in a given temperature range by adjusting the content. The expansion coefficient and Curie point increase with the increase of the content. This alloy is a widely used sealing structural material in the electric vacuum industry.
