A crystallographically textured metallic substrate includes surfaces for connection and for receiving a thin layer deposit, and is made up of an alloy presenting a cubic crystalline system with centered faces and a predominantly cubic crystallographic texture {100}&#x3c;001&#x3e;, the receiving surface including grains mainly presenting crystallographic planes {100} parallel to the receiving surface. The alloy is iron-nickel with weight % relative to total weight: Ni&#x2267;30%, Cu&#x2266;15%, Cr&#x2266;15%, Co&#x2266;12%, Mn&#x2266;5%, S&#x3c;0.0007%, P&#x3c;0.003%, B&#x3c;0.0005%, Pb&#x3c;0.0001%, and in the alloy: 34%&#x2266;(Ni+Cr+Cu/2+Co/2+Mn). The alloy includes up to 1% in weight of one or several deoxidizing elements chosen among silicon, magnesium, aluminium and calcium, the rest of the elements in the alloy being iron and impurities.
