Six cylinder, 5 litre, all-Hiduminium engine for the Armstrong Siddeley Special
The Hiduminium alloys or R.R. alloys are a series of high-strength, high-temperature aluminium alloys, developed for aircraft use by Rolls-Royce ("RR") before World War II.[1]
They were manufactured and later developed by High Duty Alloys Ltd.[1] The name Hi-Du-Minium is derived from that of High Duty Aluminium Alloys.
The first of these Hiduminium alloys was termed 'R.R.50' .[1] This alloy was first developed for motor-racing pistons,[2]
and was only later adopted for aircraft engine use. It was a development of the earlier Y alloy, the first of the nickel-containing light aluminium alloys.[3]
These alloys are one of the three main groups of high-strength aluminium alloys, the nickel-aluminium alloys having the advantage of retaining strength at high temperatures, making them particularly useful for pistons.
