X.3040 EFC2/T23.6.17. X.3040 - Upton Lewis Tests of Aluminium Alloys. X.3041 - Specific Gravity and Brinell Hardness tests of aluminium alloys. X.3039 - Tensile Tests of Aluminium Alloys. Herewith please receive prints of Upton Lewis Test records for 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, 1.15% 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 1.8% of antimony, the rest aluminium. 8. M2 Mirallite metal which consists of about 88% of aluminium, 9.64+ of copper .23% of zinc 1.15% tin, and .10% magnesium. The average Stanton Test figures so far obtained for these alloys are as follows-: (With the drop of the hammer .312). Contd. | ||
