INVAR 36
MATERIAL
OVERVIEW
Characteristics:
Invar is a trademark for an iron-nickel alloy
containing 35-36% nickel and characterized by an
extremely low coefficient of thermal expansion
(excellent for applications requiring no dimensional
changes with temperature variations.) Invar is strong,
tough, ductile and possesses a useful degree of
corrosion resistance. It is magnetic in the
temperature range up to 400 oF.
Applications: Precision instruments, measuring tapes,
weights, etc.
