Notes:
1、Under condition that the average coefficient of the linear expansion meets
the requirements of the standard, the content of nickel and cobalt are allowed to
deviate from the stated range.
2、The shape and dimensions of
the alloys are in compliance with YB/T5235.

Alloy 52 is used
as Glass to metal seals for electronic tubes, automotive and industriallamps,and specialty hermetic devices.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.
