Abstract

1,258,200. Making metal facing panels. VAW LEICHTMETALL - WERKE G.m.b.H. 26 June, 1970 [2 July, 1969], No. 31217/70. Heading B3A. A method of treating light metal sheet comprises submitting the sheet after heat treatment to plastic deformation by stretching or rolling to form a coarse grain structure during a subsequent heat treatment and thereafter making the grain structure visible by further stretching. The first heat treatment comprises annealing followed by quenching in water or cooling, preferably in air. Alternatively it may comprise solution treatment in conjunction with quenching in-water. The subsequent heat treatment is a solution treatment followed by quenching in water. The strength of the panels may be improved by aging, with the application of heat at 160-200‹ C. for 4-12 hours. The coarse grain effect may be accentuated by anodizing.
