Basic information

Our Nickel-Iron alloys are specifically designed to meet the rigorous standards set by ASTM F30 for sealing materials. These alloys are carefully engineered to possess the precise coefficients of thermal expansion required for effective sealing. Their primary purpose is to bridge the gap between two materials with different rates of expansion when exposed to heat, ensuring a secure and hermetic seal.

These high-quality Nickel-Iron Strip Products find extensive application in the glass to metal sealing industry. They are employed in a wide range of products, from light bulbs to hermetically sealed integrated circuits. Additionally, they are widely utilized in various electrical applications like switch-gear connections and reed switch systems.

Our Nickel-Iron alloys encompass a variety of options, including the renowned Invar® as well as alloys 42, 46, 48, and 52. We also offer other alloys upon request to cater to diverse industry needs. Each of our products is crafted with precision and adherence to industry standards, ensuring optimal performance and reliability.
