Top 10 INVAR Nickel Alloy Manufacturers in China

Introduction to INVAR Nickel Alloy

INVAR nickel alloy, also known as FeNi36, is a remarkable material with a very low coefficient of thermal expansion. This unique property makes it highly valuable in a wide range of applications where dimensional stability is crucial. The name "INVAR" is derived from "invariable," highlighting its ability to maintain a nearly constant volume over a broad temperature range.

INVAR alloys typically contain around 36% nickel and 64% iron, along with small amounts of other elements to enhance specific properties. Due to its low thermal expansion, INVAR is commonly used in precision instruments, aerospace components, optical devices, and in the construction of structures that require high dimensional accuracy, such as large telescopes and particle accelerators.
