At National Electronic Alloys, we offer the glass sealing Alloy 52 – a controlled expansion alloy that has low thermal expansion properties. It’s commonly used in the telecommunications industry in a variety of electronic applications. Alloy 52 is made 52 percent of nickel and 48 percent of iron. It’s more durable than nickel by itself. Produced with good machining properties, it’s manufactured in a controlled environment under controlled conditions.
