Abstract

1,116,377. Making composite sheet material. REYNOLDS METALS CO. 28 June, 1965 [2 July, 1964], No. 27338/65. Heading B3A. [Also in Division B5] A method of making a composite metal sheet comprises bonding together a layer of heattreatable aluminium alloy and a layer of ferrous alloy which is susceptible to hardening by thermal treatment in the temperature range for solution heat treatment of the aluminium-base alloy and heating the resulting bonded composite to effect concurrently the solution heat treatment of the aluminium-base alloy and the hardening of the ferrous alloy without disrupting the bond between the layers. The aluminium alloys are 3¢-5% copper bearing or aluminiumzinc-magnesium alloys, the strength of which is increased by quenching from 810-990‹ F. The aluminium-copper alloy may be clad on one or both sides with a thin coating of aluminiumzinc alloy. The ferrous alloy is a stainless steel sheet or mesh containing 15% chromium, 7% nickel, 1% aluminium and 2% molybdenum or one containing 17% chromium, 7% nickel and 1% aluminium. The layers are roll-bonded, with the steel at room temperature and the aluminium heated to 650-1000‹ F. The composite may comprise three layers, in which an aluminium sheet is bonded between two steel sheets or may comprise more than three layers. The composite may also include a layer of polyethylene terephthalate or biaxially oriented polypropylene, or an aluminium foil/plastics film combination or a layer of linear polyamide felt or woven fibre. Particularly when the composite includes a layer of one of the above non- metallic materials the bonding may be achieved by using an adhesive such as an epoxy-resin or a polysulphide polymer. After bonding, the composite is re-heated to 850-950‹ F. for “-1 hour and quenched in water. Nine examples are given describing the heating and rolling conditions for bonding various combinations of steel and aluminium and the strength of the resulting material.
