X.3039 X.3041) With reference to the above tests, Mr. Royce, in his memo R4/B27417, remarks "I think these tests are most valuable, and should be continued." In accordance with his instructions, therefore, we wish to have carried out a complete set of tests on the following range of alloys:- No. Designation Alloy. (1) P1 Present Standard Piston Alloy containing 87% of aluminium, 12% of copper, and less than .2% of zinc. (2) P2 An Alloy with considerably less copper than the above, namely, containing 91% of aluminium, 8% of copper, and less than .2% of zinc. (3) C Standard Crankcase Alloy, containing 2% of copper, 12% of zinc, and the rest aluminium. (4) M1 Magnalium Metal. (5) L Levitt Metal containing 96.4% of aluminium, 2.2% of copper, .5% of zinc and .2% manganese. (6) H The Metal suggested by Mr. Hall, containing approximately 94.5% of aluminium, 2.5% to 3.2% of copper, 1.5 to .5% of zinc, .8 to 1.5% of antimony, and 1.0 to 1.5% nickel. (7) A Aluminium Copper Antimony Alloy, containing 10% of copper and 1.2 to 1.7% of antimony, the rest aluminium. (8) M2 Mirallite Metal which consists of about 88% of aluminium, 9.64% copper, .23% of zinc, 1.15% tin and .10% of magnesium. Contd. | ||
