How hard is invar
WebThe graduation of the precision Invar levelling staffs is engraved in the paint coating with an interferometrically controlled laser beam, ensuring superior graduation accuracy and edge sharpness. The permissible deviation is ΔL ≤ 0.01 + l ∙ 10-5. Nedo Invar levelling staffs thus conform to the highest accuracy class A as per DIN ISO ... Web13 nov. 2024 · So, what exactly is Invar? Well, generically, it is known as "FeNi36" or, in the US, "64FeNi." In other words, it is a nickel-iron alloy, with a uniquely low coefficient of thermal expansion. It is described as being a "single-phase" alloy because it is a solid solution consisting of about 36% nickel and 64% iron.
