Hite Special Alloy is a high-tech enterprise, mainly engaged in the production of Hastelloy, Monel, Inconel, nickel and other high-temperature alloys.
4J32 alloy is also called Super-Invar alloy. In -60℃ to 80℃ temperature range the expansion coefficient is lower than that of 4J36, but the low temperature structure stability is not good as that of 4J36.
It has low and nominally constant coefficient of thermal expansion from room temperature to about 300℃.
It maintains nearly constant dimensions over the range of normal atmospheric temperatures, and has low coefficient of expansion from cryogenic temperatures to about 500o F(260℃).
Its coefficient of expansion matches the expansion rate of borosilicate glasses and alumina ceramics.
