Metal Alloys - Specific Heats
The specific heat capacity of some common metal alloys are indicated in the table below:
| Metal alloy | Specific Heat - cp - | |
|---|---|---|
| (kJ/(kg K)) | (Btu/(lb oF)) | |
| Admiralty Brass | 0.38 | 0.09 |
| Aluminum Bronze | 0.38 | 0.09 |
| Ball metal | 0.360 | 0.086 |

| Brass | 0.377 | 0.090 |
| Bronze | 0.435 | 0.104 |
| Hasteloy | 0.38 | 0.091 |
| Inconel | 0.46 | 0.11 |
| Incoloy | 0.50 | 0.12 |
| Manganese Bronze | 0.38 | 0.09 |
| Monel | 0.53 | 0.127 |
| Nickel steel | 0.456 | 0.109 |
| Red Brass | 0.38 | 0.09 |
| Solder 50/50 Sn Pb | 0.167 | 0.04 |
| Yellow Brass | 0.38 | 0.09 |
Heating Energy
The energy required to heat a product can be calculated as
q = cp m dt (1)
where
q = heat required (kJ)
cp = specific heat (kJ/kg K, kJ/kg oC)
dt = temperature difference (K, oC)
Example - Required Heat to increase Temperature in Bronze
10 kg of bronze is heated from 20 oC to 100 oC - a temperature difference 80 oC (K). The heat required can be calculated as
q = (0.435 kJ/kg K) (10 kg) (80 oC)
= 348 kJ
