This alloy is also known generically as FeNi36 (64FeNi in the US). Invar is 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.

WebWhat is the advantage of copper-constantan over iron-constantan? Explanation: Copper-constantan differs from iron-constantan due to the use of copper instead of iron, along with the possible addition of manganese and iron. This is useful for measuring low temperatures up to -420 F and a maximum limit of 600 F. WebIron-constantan thermocouples (Type J) have a sensitivity of 55 μV/°C and are the preferred type for general purpose measurements in the temperature range of −40°C to +750°C, where the typical measurement inaccuracy is ±0.75%.
