It is desired to carry out tests of an alloy of the following composition:which has been proposed by the R.A.F.:- Copper 7% Zinc 1% Tin 1% Aluminium 91% The tests should comprise the same tests aswe instructed for the previous range of alloys under EFC4/T9.5.17 viz.- (a) Stanton impact test (3 test pieces) (b) Upton Lewis Fatigue test (3test pieces) (c/d)Tensile tests at atmospheric temperature and higher temperatures up to 400°C. (6test pieces) (E) Specific Gravity & Brinell hardness tests. (F) Chemical Analyses. Will those concerned kindly note and endeavour to put these tests through with the least possible delay. EFC. | ||
