Abstract

1,047,513. Making composite sheets, jewellery; welding by pressure. E. I. DU PONT DE NEMOURS & CO. April 19, 1963 [May 2, 1962], No. 15604/63. Addition to 923,746. Headings B3A and B3R. [Also in Division C7] A method of making thin clad metal sheets comprises forming a composite metal sheet from at least two metals by explosive cladding and cold rolling through tandem or reversing mills the composite thus formed to reduce its thickness by 20-90% of its original thickness. The cladding metals, which may be applied on one or both sides of the backing metal, comprise copper and alloys thereof, titanium and alloys thereof, tantalum and alloys thereof, gold, silver, palladium, iridium, rhodium, stainless steel, zirconium and alloys thereof, chromium and alloys thereof, nickel and alloys thereof e.g. " Inconel " (Registered Trade Mark) and " Invar " (Registered Trade Mark), " Hastelloys " (Registered Trade Mark), " Monel " (Registered Trade Mark), nickelsilver and "Nichrome " (Registered Trade Mark). The backing metals may comprise steel, stainless steel nickel, aluminium or copper. The composite may be subject to interstage annealing in an inert atmosphere e.g. of argon or in vacuo. Interstage descaling may be carried out in a sodium hydroxide bath containing 2% sodium hydride for up to one hour in aqueous nitric or sulphuric acid solutions or by abrasive action using a polishing wheel dependent upon the metals used. In examples 0À0508 cm. thick titanium is clad, on 0À477 cm. thick killed steel; 0À0762 cm. tantalum on 0À635 cm. mild steel; 0À159 cm. gold on 1À27 cm. nickel; 0À0254 cm. stainless steel on 0À19 aluminium alloy; 0À063 cm. stainless steel on 0À635 cm. low carbon steel. In the examples the -annealing temperatures are given as 700‹ C. for 20 minutes, for titanium/killed steel and gold/ nickel, 110‹ C. in a vacuum furnace for tantalum/mild steel, 600‹ C. for 15 minutes for stainless steel/aluminium alloy and 1650‹ F. for 5 minutes for stainless steel/low carbon steel. The noble metals are clad on to nickel for use on jewellery.
