Light alloys now play a most important part in aircraft construction. It is probable that they will keep their present superiority over other materials which have been in use, because manufacturers are continually adapting light alloys to the need of the day.
Light alloys have, however, formidable rivals. There are many arguments for the use of wood, and we must recognise that in certain aspects (such as resistance to vibration and ease of working) the use of wood has definite advantages, particularly in the case of plywood.
