4J36 Invar 36 Controlled Expansion Alloy Foil Thickness 0.005-0.05mm
1 . Descriptions:
Invar Alloy Foil is available in numerous thicknesses and tempers for applications requiring high dimensional stability and low thermal expansion.
Generally immediately available in most volumes,available in machined shapes such as bar,ingot,ribbon,wire,shot ,sheet,and foil.
Typical and custom packaging is available,as is additional research,technical and safety data.
invar 36 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 form cryogenic temperatures to about +500℃.Invar 35 also retains good atrength and thoughness at cryogenic temperature.
