X.3040 - UPTON LEWIS TESTS OF ALUMINIUM ALLOYS. X.3041 - SPECIFIC GRAVITY TESTS. Herewith please receive prints of Upton Lewis test records for 2 sample Magnalium metals which we have been able to obtain. The specific gravities of these two samples are as follows:- M.3 2.75 M.4 2.91 Sample M.3 is Magnalium metal converted by Messrs. Blackwell, The Albany, Liverpool, to Magnalium from aluminium supplied to them. Sample M.4 is magnalium obtained from the Metropolitan Foundry, Barnes Bridge, London, S.W. EFC. | ||
