WebInvar, also known generically as FeNi36 (64FeNi in the US), is a nickel–iron alloy notable for its uniquely low coefficient of thermal expansion (CTE or α). The name Invar comes from the word invariable, referring to its relative lack of expansion or contraction with temperature changes.. The discovery of the alloy was made in 1895 by Swiss physicist Charles … WebKOVAR - alloy K (1.3981) The lowest CTE Between 20-500 ºC and equal to glass and ceramics. Created in 1930. This Ni-Co alloy has two typical applications. Between 20-500 °C, KOVAR (alloy K) has the lowest CTE of all alloys or metals. But its CTE is also equal to glass and ceramics. Making it an ideal metal to seal glass metal or ceramic-metal.
