X.3039 X.3041) With reference to the above tests, Mr. Royce, in his memo RM{William Robotham - Chief Engineer}/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) #1 Present Standard Piston Alloy containing 87% of aluminium, 12% of copper, and less than .2% of zinc. (2) F2 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% [handwritten '4' above] manganese. (6) H The Metal suggested by Mr. Hall, containing approximately 93.5% of aluminium, 2.5% to 3.2% of [handwritten 'copper of' above] zinc, .8 to 1.5% of antimony, and 1.0 to 1.5% nickel. [handwritten '1 - 1.5 Zn' below] (7) A Aluminium Copper Antimony Alloy, containing 10% of copper and [typed, struck through: 1.2 to 1.7%] [handwritten: 2.0 to 2.7%] of antimony, the rest aluminium. (8) MB Mirallite Metal which consists of about 88% of aluminium, 9.64% copper, .23% of zinc, 1.15% tin and .10% of magnesium. Contd. | ||
