Aluminium Exports 19. Mr. J. Grimston asked the Minister of Supply what steps were taken to verify that the 620 tons of aluminium, for which an export licence was granted in 1949, were unsuitable for sale in Britain. Mr. G. R. Strauss The 620 tons referred to consisted of four separate parcels. They were all of low-grade secondary aluminium, and before agreeing to their export advice was obtained either from the Aluminium Industry Advisory Committee or the Federation of Secondary Light Smelters.
