1.3912 Ni36 UNS K93600 low expansion sealing alloy China factory

Introduction

Invar is a low expansion alloy consisting of 36% Nickel, balance Iron. Invar Alloy exhibits extremely low expansion around ambient temperatures, making Invar Alloy particularly useful in applications where minimum thermal expansion and high dimensional stability is required,  such as in precision instruments like optoelectronic devices, optical and  laser benches, electronics, and other kinds of scientific instruments.

Character

Low expansion rate up to 500°F

Readily weldable

Application

Cathode Ray Tubes

Other application areas, such as telecommunications, aeronautical and aerospace engineering, cryogenic engineering (liquefied natural gas tankers) etc., require either high dimensional stability with variation in temperature, or expansion characteristics  matched with those of other materials, such as glass, ceramics, or  composites.
