Lightweight High Specific Heat Capacity Materials

smooth operater

Anyone know of any lightweight materials that have a high specific heat capacity?

Preferrably some material I could get my hands on...

Something better than water

High specific heat capacity and Lightweight are relative terms and it depends on the application... i.e. what is you max application temp, cycling temp... Perhaps Aluminium alloy or Titanium might be suitable?

Thank you good sir, seems water is a bit of a winner

Ye i understand there relative alright, but for 1kilo of water it'll take more energy to heat it up than 1kg of air, just didn't know how to phrase it as such.

Running temp is gonna be around 80degreesC, so i was hoping, i could get something maybe 1m^3 and heat it up, just metals are quite heavy and expensive

1 cubic meter is a friggin massive amount of metal. about 7 1/2 tonnes of steel.

presuming that you need the material to act as a heat sink, circulating water through copper pipes would be easier and cheaper.

Ye reckon?
