Precision Alloy

Expansion Alloy

    Standards: ASTM F 1684-06

     

    Equal grades: Invar 36, NILO 36, Pernifer 36, 4J36, EN  1.3912, UNS K93600, UNS K93603, Werkstoff 1.3912

Products detail:
Super Invar, a magnetic, austenitic, solid solution  alloy containing iron, nickel, and cobalt, is designed to provide minimum  thermal expansion at room temperatures. This alloy also exhibits austenite  stability to service temperature at least -67°F and thermal expansion  properties less than those of Invar 36 alloy (36% nickel-iron) when used in  the -67/203°F (-55/95°C) temperature range.
Equal grades:
Invar 36, NILO 36, Pernifer 36, 4J36, EN  1.3912, UNS K93600, UNS K93603, Werkstoff 1.3912
Standards:
ASTM F 1684-06
Forms available:
Sheet, strip, wire, rod, bar, tube, capillary

Chemical  composition:
