Invar 36®
MATERIAL OVERVIEW
Characteristics: Invar 36® 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.
