Good Quality Alloy 926 Round Bar - Expansion Alloy Invar36-4J36 Sheet/Bar/Strip/Tube – Sekonic
Good Quality Alloy 926 Round Bar - Expansion Alloy Invar36-4J36 Sheet/Bar/Strip/Tube – Sekonic Detail:
Common Trade Names: Invar alloy,4J36,Invar,UNS k93600 (FeNi36),Nilo36,Pernifer 36, Invar Steel,36H/36H-BИ、Unipsan 36
It is a Nickel-Iron, low expansion alloy containing 36% Nickel with balance of Iron. It maintains nearly constant dimensions over the range of normal atmospheric temperatures and has a low coefficient of expansion from cryogenic temperatures to about +500°C. Nilo 36 also retains good strength and toughness at cryogenic temperatures. Applications include standards of length, thermostat rods, laser components and tanks and piping for the storage and transportation of liquefied gasses.
