Correct ,just did some checking,
The sinking of the Sheffield is sometimes blamed on a superstructure made wholly or partially from aluminium, the melting point and ignition temperature of which are significantly lower than those of steel. However, this is incorrect as the Sheffield's superstructure was made entirely of steel. The confusion is related to the US and British Navies abandoning aluminium after several fires in the 1970s involving ships that had aluminium superstructures. The sinking of the Type 21 frigates HMS Antelope and Ardent, both of which had aluminium superstructures, probably also had an effect on this belief though these cases are again incorrect and the presence of aluminium had nothing to do with their loss. In both cases, it is likely the ships would have been lost in any event, due to amount of explosives involved in such small ships, though aluminium fires did break out. Ardent in particular took a severe pounding, suffering eleven bomb hits, five of which exploded; no ship of her type of any era would have been able to survive such an attack. The fires on these ships did result in one clear change, which was the shift away from the nylon and synthetic fabrics then worn by British sailors. The synthetics had a tendency to melt on to the skin causing more severe burns than if the crew had been wearing non-synthetic clothing. The official report into the sinking of Sheffield, recently disclosed under UK Freedom of Information laws after an extensive campaign by ex-RN personnel, severely criticised the ship's fire-fighting equipment, training and procedures and certain members of the crew
