Beschreibung
Zusammenfassung:	A weldable, corrosion-resistant copper/nickel alloy having good hot workability and high tensile strength is composed of 4 to 22% nickel, up to 3% manganese, up to 3% iron, up to 0.3% silicon, up to 4% chromium, 0.005 to 0.2% carbon and 0.1 to 4% of at least one of the elements titanium, vanadium, zirconium, niobium, tantalum or hafnium, the remainder, including unavoidable impurities, being copper. This corrosion-resistant alloy is remarkable for an improved weldability and hot workability, and also a weld additive which is suitable for this purpose. L'INVENTION CONCERNE UN ALLIAGE CUIVRE-NICKEL APTE AU SOUDAGE, RESISTANT A LA CORROSION, ET PRESENTANT UNE BONNE DEFORMABILITE A CHAUD ET UNE GRANDE RESISTANCE A LA TRACTION. CET ALLIAGE EST COMPOSE DE:-4 A 22 DE NICKEL;-JUSQU'A 3 DE FER;-JUSQU'A 0,3 DE SILICE;-JUSQU'A 4 DE CHROME;-DE 0,005 A 0,2 DE CARBONE,-ET AU MOINS L'UN DES ELEMENTS TITANE, VANADIUM, ZIRCONIUM, NIOBIUM, TANTALE OU HAFNIUM DANS LA PROPORTION DE 0,1 A 4, DES RESIDUS DE CUIVRE Y COMPRIS DES IMPURETES INSEPARABLES.
