| To DPC. from R.{Sir Henry Royce} c. to I c. to FH. c. to Na.{Mr Nadin} ORIGINAL R9/B2:6:17. D 3 6 JUN 1917 RECEIVED X 2749 X 3069 Re Aluminium Copper Alloy for Pistons. Since it is evident that the aluminium copper alloy for pistons is very brittle, I should like a set of pistons tested having 8% of copper and 92% of aluminium. I should be glad to know whether this is a better metal as regards casting, that is, less liable to disintegrate. If we are satisfied that it is a better casting metal and behaves better in the engine, we could ask the Air Board to allow us to use it ~~in the engine~~. R.{Sir Henry Royce} | ||
