Product Description

 *Invar 36 alloy, ASTM F1684, UNS k93600 (FeNi36), Chinese 4J36

 

Invar alloy is  A Nickel Iron, low expansion alloy containing 36% Nickel. 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.

Notes:1. Under condition that the average coefficient of the linear expansion meets the requirements of the standard, the content of nickel and cobalt 

are allowed to deviate from the stated range.

2.  The shape and dimensions of the alloys are in compliance with GB/T14985.We could do any other products with specified technical standard, say,

 ASTM,SAE,DIN,S.E.W.,JIS,ISO,IEC,NF,BS.PLS email us about your standard requests.
